I’m surrounded by idiots.
I’m continually reminded of that fact, but today I found something that really drives that point home.
Gather ‘round, everybody, it’s story time!
While working on a slow query ticket, I perused the code, finding several causes, and decided to run git blame on the files to see what dummy authored the mental diarrhea currently befouling my screen. As it turns out, the entire feature was written by mister legendary Apple golden boy “Finder’s Keeper” dev himself.
To give you the full scope of this mess, let me start at the frontend and work my way backward.
He wrote a javascript method that tracks whatever row was/is under the mouse in a table and dynamically removes/adds a “.row_selected” class on it. At least the js uses events (jQuery…) instead of a `setTimeout()` so it could be worse. But still, has he never heard of :hover? The function literally does nothing else, and the `selectedRow` var he stores the element reference in isn’t used elsewhere.
This function allows the user to better see the rows in the API Calls table, for which there is a also search feature — the very thing I’m tasked with fixing.
It’s worth noting that above the search feature are two inputs for a date range, with some helpful links like “last week” and “last month” … and “All”. It’s also worth noting that this table is for displaying search results of all the API requests and their responses for a given merchant… this table is enormous.
This search field for this table queries the backend on every character the user types. There’s no debouncing, no submit event, etc., so it triggers on every keystroke. The actual request runs through a layer of abstraction to parse out and log the user-entered date range, figure out where the request came from, and to map out some column names or add additional ones. It also does some hard to follow (and amazingly not injectable) orm condition building. It’s a mess of functional ugly.
The important columns in the table this query ultimately searches are not indexed, despite it only looking for “create_order” records — the largest of twenty-some types in the table. It also uses partial text matching (again: on. every. single. keystroke.) across two varchar(255)s that only ever hold <16 chars — and of which users only ever care about one at a time. After all of this, it filters the results based on some uncommented regexes, and worst of all: instead of fetching only one page’s worth of results like you’d expect, it fetches all of them at once and then discards what isn’t included by the paginator. So not only is this a guaranteed full table scan with partial text matching for every query (over millions to hundreds of millions of records), it’s that same full table scan for every single keystroke while the user types, and all but 25 records (user-selectable) get discarded — and then requeried when the user looks at the next page of results.
What the bloody fucking hell? I’d swear this idiot is an intern, but his code does (amazingly) actually work.
No wonder this search field nearly crashed one of the servers when someone actually tried using it.

Why is Java so comfy?
I don't know why, but every time I try to use Javascript and Python I feel lost in those functional gimmicks and fancy libraries.
Java feels like the warm, soft old couch at home.9 -
Let the student use their own laptops. Even buy them one instead of having computers on site that no one uses for coding but only for some multiple choice tests and to browse Facebook.
Teach them 10 finger typing. (Don't be too strict and allow for personal preferences.)
Teach them text navigation and editing shortcuts. They should be able to scroll per page, jump to the beginning or end of the line or jump word by word. (I am not talking vi bindings or emacs magic.) And no, key repeat is an antifeature.
Teach them VCS before their first group assignment. Let's be honest, VCS means git nowadays. Yet teach them git != GitHub.
Teach git through the command line. They are allowed to use a gui once they aren't afraid to resolve a merge conflict or to rebase their feature branch against master. Just committing and pushing is not enough.
Teach them test-driven development ASAP. You can even give them assignments with a codebase of failing tests and their job is to make them pass in the beginning. Later require them to write tests themselves.
Don't teach the language, teach concepts. (No, if else and for loops aren't concepts you god-damn amateur! That's just syntax!)
When teaching object oriented programming, I'd smack you if do inane examples with vehicles, cars, bikes and a Mercedes Benz. Or animal, cat and dog for that matter. (I came from a self-taught imperative background. Those examples obfuscate more than they help.) Also, inheritance is overrated in oop teachings.
Functional programming concepts should be taught earlier as its concepts of avoiding side effects and pure functions can benefit even oop code bases. (Also great way to introduce testing, as pure functions take certain inputs and produce one output.)
Focus on one language in the beginning, it need not be Java, but don't confuse students with Java, Python and Ruby in their first year. (Bonus point if the language supports both oop and functional programming.)
And for the love of gawd: let them have a strictly typed language. Why would you teach with JavaScript!?
Use industry standards. Notepad, atom and eclipse might be open source and free; yet JetBrains community editions still best them.
For grades, don't your dare demand for them to write code on paper. (Pseudocode is fine.)
Don't let your students play compiler in their heads. It's not their job to know exactly what exception will be thrown by your contrived example. That's the compilers job to complain about. Rather teach them how to find solutions to these errors.
Teach them advanced google searches.
Teach them how to write a issue for a library on GitHub and similar sites.
Teach them how to ask a good stackoverflow question :>6 -
I couldn't sleep. I was staring at the blinking cursor. A slow, comforting blinking. Like everyone else, I had become a slave to the JavaScript ecosystem. If I saw something like a new build system, or a new framework, I had to have it.
My client changed the requirements again. I'm in pain.
- "You want to see pain?" my colleague said. Go read Apple support forums. That's pain.
I became addicted. Every time I died and every time I was born again. Resurrected.
During the night, I was crying in the Apple forums for an official answer that would never come. During the day, I was surfing StackOverflow to fix my problems. You get "single-serving" friends there. They help you, you help them, and then you never see them again.
- "Then you install Stack and boom, you're done. It's that easy to go functional."
That's how I met him.
- "You know why they make so many javascript frameworks?"
- "No, why?"
- "So that they can distract you while they put backdoors in them. So that you don't have time to check all of their code".
- "You are by far the most interesting "single-serving" friend I've ever met"
Then, my hard disk died. Of course, I didn't have backups: nobody has enough space for all those node_modules folders. All my addictions, lost.
Then I wrote him. If you asked me now, I couldn't tell you why I wrote him. We chatted a lot.
- "It's late, I should really go search another hdd on ebay"
- "Ebay? You called me so you could have my old hard disk."
- "No, I..."
- "Come on."
He sent me his old hard disk. It was a 256MB hard disk, but it was fine for running Arch. Then he asked me to rant about my problems in front of him.
- "I want you to rant as hard as you can"
- "Are you serious?"
We ranted all night about our bosses and clients and their fucked up requests. We kept in touch, and after a while more people were ranting with us. Every week, he gave the rules that he and I decided.
- "The first rule of devRant is -- you don't talk about devRant. The second rule of devRant is -- you don't talk about devRant."
I like to think this is how devRant started. This might also be the reason why we never see @trogus, only @dfox. A lot of shit still needs to happen.8 -
Once got 3rd place in a company "code golf". It was open to any language or platform.
I built a functional minesweeper game in Excel with 600 lines of code, complete with color and animation.

Yknow, I want to make an android app that I have in my mind for about half a year now and I already tried twice, both with Kotlin and with Java but everytime I try it's just pain and suffering and frustration...
No it's not because of the language, I like Java and I like Kotlin too and I'd say I'm at least decent at Kotlin and really good in Java...
No no.. the issue is the fucking Android SDK and the mix-and-match documentation available online!!!
Every fucking time I want to implement some sort of UI element, user action or a background service and I start googling how to do it It comes with with at least 3 different stack overflow solutions, all of them saying "that way of doing it is deprecated, instead you should X" and looking up the OFFICIAL FUCKING DOCS it will just make me roll up in the corner and cry because of how fucking inconsistent it is and the retarded domain language it uses... fucking transactions for fucking fragments inside fucking activities... because I guess the word "screen"/"view"/"template" or something similar natural just was too mainstream for the all knowing alphabet soup that google is...
And then you start looking up what the fucking difference even is and how to code it up only to find out there's at least 12 other opinions on how fragments should be used and what should be an activity and what should be a damn fragment...
But that's not all, that's just the base... I get a headache even thinking about how the fucking inflating of templates and the entire R. notation works. You want to open a fucking tiny corner menu with the settings options? WELL THEN YOU FUCKING BETTER REMEMBER TO IMPLEMENT IT THROUGH SOME SORT OF EVENT AND INFLATE THE MENU YOURSELF EVEN THOUGH ITS THE SAME FUCKING THING WITH STATIC STRINGS...
AND WHY THE FUCK DO I NEED LIKE 4 NEW FILES TO IMPLEMENT A FUCKING LISTVIEW...
also talking about ListViews... what was wrong with "ListView"... Why do we need a "RecyclerView"... oh right... because the fucks fucked the fuck up and all the legacy components were designed by a monkey and are next to useless! SO WE NEEDED A NEW NAME FOR THE FIXED VERSION, CANT NAME IT LISTVIEW AGAIN... FUCK YOU...
honestly... if I got a dolar for every "what the fuck android" I said during trying to understand that mess I'd be richer by a few hundred...
oh oh oh, but you know what? You don't like the android SDK? that's fine, you can use fucking React or Flutter or something... yeah.. because instead of torturing myself with the android SDK I want to torture myself with an abstraction of the same SDK and JavaScript as the fucking cherry on top... HAVE YOU FUCKING SEEN THE CODE FLUTTER SHOWS ON THEIR WEBSITE AS THE "Introduction" ?!!!
Look at this piece of shit:
[code in attached image, we could really use a proper Markdown support at least for rants]
THAT'S NOT EVEN THE ENTIRE THING, THAT'S JUST THE *REALLY* UGLY PART...
The fucking nesting... What is it with JS and all the fucking nesting everytime?! It looks like shit.... It reads like shit as well...
WHY, in the name OF FUCK, IS THERE MORE THAN 5 ANDROID FRAMEWORKS and ALL of them... used this FUCKING NOVEL idea of programming using A FUCKING BRACKET WALL
It always looks like:
(code(code[code{code(code{code()})}]));
If I wanted to make a fucking app or a website using fucking Haskell I'd do that.... at this point reading assembly code feels like heaven compared to this retardation... Why is this so popular?! WHAT DO YOU PEOPLE SEE IN IT?! Clearly it's not the aesthetics... it looks like a fucking frog vomit running down an emus leg, fuck that.... I don't even hate classic JavaScript, it's a good enough language and it does what I tell it to... but these ugly fucking frameworks like react, angular and whatever else uses this fucking format can go fuck right off. This is not the way JS is gonna get a better name for itself...
So:
Fuck Google
Fuck the marionette that designed the Android SDK
Fuck the Hellspawn the came up with the "functional-like" way of using JavaScript
Fuck everyone that thinks "JavaScript everywhere" is a good thing
And deeply future-fuck everyone that makes a new framework following any of these standards, stucks a .js at the end of the name and releases his hairball.js of an invention into the fucking world....
It's a mess... fuck everything android related...

Oh, this PHP thing is becoming big, we must use this; *makes ASP*
Oh, oh, this Java thing is really popular, and we're not the big bois now! *releases C#*
Waaait, functional is cool now? Damnit. Dude, grab this~~~ *F#*
Uhh. So people actually like JavaScript now? A wild *~~TypeScript~~* has appeared

A year ago I ranted, that I understood JavaScript callbacks.
That was a lie. I knew nothing.
But I think I scratched the surface by getting into functional programming this time.3 -
fuck these websites thAT ARE GETTING SO GOD DAMN HEAVY THEY LOAD WHEN I TURN OFF THE WIFI.
literally just fuckin shut off the wifi while this one bloated, shitty website loading aND THE WEBSITE DISPLAYED. of course, the gigabytes of javascript haven't loaded so the buttons weren't functional, bUT AT LEAST I COULD SEE THE CONTENT INSTEAD OF A WHITE SCREEN.
if ur gonna have a shitload of assets at least make your websites be viewable while the page is loading13 -
First Post since... Long I guess?
I got a new project!! I am currently creating a Webserver Framework in Java. I can create fully functional websites with a few lines of JSON.
(Look below)
Currently I don't have direct Javascript support, but I am working on installable modules. With those the Web-Admin can code little code fragments that can be shown (live) on the webpage.
I am so hyped because it does work <3
(Pictures of development might follow)
(Can I even call it framework? Hm dunno.. )

Why is it that virtually all new languages in the last 25 years or so have a C-like syntax?
- Java wanted to sort-of knock off C++.
- C# wanted to be Java but on Microsoft's proprietary stack instead of SUN's (now Oracle's).
- Several other languages such as Vala, Scala, Swift, etc. do only careful evolution, seemingly so as to not alienate the devs used to previous C-like languages.
- Not to speak of everyone's favourite enemy, JavaScript…
- Then there is ReasonML which is basically an alternate, more C-like, syntax for OCaml, and is then compiled to JavaScript.
Now we're slowly arriving at the meat of this rant: back when I started university, the first semester programming lecture used Scheme, and provided a fine introduction to (functional) programming. Scheme, like other variants of Lisp, is a fine language, very flexible, code is data, data is code, but you get somewhat lost in a sea of parentheses, probably worse than the C-like languages' salad of curly braces. But it was a refreshing change from the likes of C, C++, and Java in terms of approach.
But the real enlightenment came when I read through Okasaki's paper on purely functional data structures. The author uses Standard ML in the paper, and after the initial shock (because it's different than most everything else I had seen), and getting used to the notation, I loved the crisp clarity it brings with almost no ceremony at all!
After looking around a bit, I found that nobody seems to use SML anymore, but there are viable alternatives, depending on your taste:
- Pragmatic programmers can use OCaml, which has immutability by default, and tries to guide the programmer to a functional programming mindset, but can accommodate imperative constructs easily when necessary.
- F# was born as OCaml on .NET but has now evolved into its own great thing with many upsides and very few downsides; I recommend every C# developer should give it a try.
- Somewhat more extreme is Haskell, with its ideology of pure functions and lazy evaluation that makes introducing side effects, I/O, and other imperative constructs rather a pain in the arse, and not quite my piece of cake, but learning it can still help you be a better programmer in whatever language you use on a day-to-day basis.
Anyway, the point is that after working with several of these languages developed out of the original Meta Language, it baffles me how anyone can be happy being a curly-braces-language developer without craving something more succinct and to-the-point. Especially when it comes to JavaScript: all the above mentioned ML-like languages can be compiled to JavaScript, so developing directly in JavaScript should hardly be a necessity.
Obviously these curly-braces languages will still be needed for a long time coming, legacy systems and all—just look at COBOL—, but my point stands.7 -
One day after typescript , I ditch JavaScript on es5 totally and my college education on objective orient finally pays off ! !
I love functional programming but still insist that objective oriented is better for large project

FUCK FUCK FUCK Driven Development2 -
How the Common Lisp Community will eventually die soon:
Clojure is the only main Lisp dialect having some sort of heavy presence in today's modern development world. Yes, I am aware of other(if not all) environments in which Lisp or a dialect of it is being used for multiple things, CADLisp, Guile Scheme, Racket, etc etc whatever. I know.
Not only is Clojure present in the JVM(I give 0 fucks about whether you like it or not also) but also has compilation targets for Javascript via Clojurescript. This means that i can effectively target backend server operations, damn near everything inside of the JVM and also the browser.
Yet, there is no real point in using Lisp or Clojure other than for pure academic endeavours, for which it is not even a pure functional programming language, you would be better served learning something else if you want true functional purity. But also because examples for one of the major areas in software development, mainly web, are really lacking, like, lacking bad, as in, so bad most examples are few in between and there is no interest in making it target complete beginners or anything of the like.
But my biggest fucking gripe with Lisp as a whole, specifically Common Lisp, is how monstrously outdated the documentation you can find available for it is.
Say for example, aesthetics, these play a large role, a developer(web mostly) used to the attention to detail placed by the Rails community, the Laravel community, django, etc etc would find on documentation that came straight from the 90s. There is no passion for design, no attention to detail, it makes it look hacky and abandoned. Everything in Lisp looks so severely abandoned for which the most abundant pool of resources are not even made present on a fully general purpose language constrained as a scripting environment for a text editor: Emacs with Emacs Lisp which I reckon is about the most used Lisp dialect in the planet, even more so than Clojure or Common Lisp.
I just want the language to be made popular again y'know? To have a killer app or framework for it much like there is Rails for Ruby, Phoenix for Elixir, etc etc. But unless I get some serious hacking done to bring about the level of maturity of those frameworks(which I won't nor I believe I can) then it will always remain a niche language with funny syntax.
To be honest I am phasing away my use of Clojure in place of Pharo. I just hate seeing how much the Lisp community does in an effort to keep shit as obscure and far away from the reach of new developers as possible. I also DESPISE reading other Lisp developer's code. Far too fucking dense and clever for anyone other than the original developer to read and add to. The idea that Lisp allows for read only code is far too real man.
Lisp has been DED for a while, and the zombies that remain will soon disappear because the community was too busy playing circle jerks for anything real to be done with it. Even as the original language of AI it has been severely outshined by the likes of Python, R and Scala, shit, even Javascript has more presence in AI than Lisp does now a days.9 -
Oh yeah am very religious.

I was talking to a friend about the current state of machine learning through tensorflow and commented about the use of Javascript as a language.
He discarded the idea as he views Javascript as something that should only be used as a frontend technology rather than something to build backends or deep learning models.
I am thorn. I have always liked Javascript but will admit that I have used it mostly in the area of front end with very few backend instances(i did create a full stack intranet app in Express once, major success for the application it was hosting, it was a very basic api which had its own nosql db with no need to interact with the company's relational data, it was perfect for the occasion and still help maintaining it from time to time)
My boi states that node's biggest issue has always been npm and the quality of packages. I always contradict those statements by saying that if one uses community standards and the best packages then one does not need to worry about the quality(i.e mongoose over some unmaintained mongo wrapper etc)
I sometimes catch myself finding that my way of thinking adapts better to JS than it even does Python (which is his preference for deep learning) and whilst there are some beastly packages for python in terms of quality and usefulness such as matplotlib etc that one can do great things with the equivalent JS.
I mean, tensorflow.js came from the same wizards that did tensorflow (obviously) and i find the functional approach of JS to be more on par with how we develop solutions.
I am no deep learning expert, and sadly I have no professional experience with machine learning. But I venture to say that we should not cast aside the great strides that the JS community has done to the language in terms of evolution and tooling. Today's Js is not your grandaddy's Js and thinking that the language is crippled because of early iterations of the language would be severely biased.
What do you guys(maybe someone with professional experience) think of Js as a language for machine learning?
Do you think the language poses something worth considering in terms of tooling and power for ml?2 -

I read the pragmatic programmer a few months ago. The book advised learning a different programming language every month or so. I was doing Advent of Code so I decided to try out Elm because functional programming is all the rage these days.
It took me one hour to convert a string of numbers to an array of numbers! And when I finally finished with that I couldn't understand how to compare each element with the next one in an array using map or filter.
I realised that I've become too comfortable using javascript. Worst case scenario: In a few years when javascript is obsolete I'll be like those old dudes that know only Cobol. Best case scenario: I'll always be too dumb to earn a nice salary.
On a positive note: The first time I tried Elm I didn't understand jack shit, now I understood a few things.5 -
Trying out pure functional programming in javascript. First few weeks: wow, this is so fresh, oop can die, etc. Now: this isn't readable at all! 😐5

Anyone in here successfully using a pure FP language/ecosystem on their day to day?
I know of one of you that uses Scala, and myself I have an (admittedly) shitty application at work running in Clojure. These last two languages I mentioned are not pure FP.
I am talking about the likes of PureScript, Haskell, etc. Those mfkas.
If so,what is your experience working in said paradigm? I tried to keep my Clojure program as pure as possible, I failed, but enjoyed it.
And I know that FP is not a silver bullet, but in some scenarios when properly applied it can work beautifully. I also have React based applications with pure components, but Javascript itself is neither a functional(pure or otherwise) programming language, it merely supports functional paradigms.
Just wondering, no flamewars or anything like that, I just want to know your pros and cons.6 -
Lead: alright people what are your ideas and updates for this page refactor we've been talking about.

It was COMPLETE GARBAGE. He used 1,500+ lines of js in 17 files to make what was essentially a simple 2 item list.
We were looking at a way to overhaul the entire page, he "refactored" maybe perhaps 5% of the page.
There was absolutely nothing clean / functional / composable about this monstrosity. It was as if he read chapter 1 of a book on functional programming and decided he understood enough to call himself an expert.

I just released my first NPM package that is actually functional and used in a private project (https://npmjs.com/package/@lbfalvy/...) and I have to say, the quality of debug tooling for Node is abysmal.

!rant
For all of youse that ever wanted to try out Common Lisp and do not know where to start (but are interested in getting some knowledge of Common Lisp) I recommend two things:
As an introductory tutorial:
https://lisperati.com/casting.html/
And as your dev environment:
https://portacle.github.io/
Notice that the dev environment in question is Emacs, regardless of how you might feel about it as a text editor, i can recommend just going through the portacle help that gives you some basic starting points regarding editing. Learn about splitting buffers, evaluating the code you are typing in order for it to appear in the Common Lisp REPL (this one comes with an environment known as SLIME which is very popular in the Lisp world) as well as saving and editing your files.
Portacle is self contained inside of one single directory, so if you by any chance already have an Emacs environment then do not worry, Portacle will not touch any of that. I will admit that as far as I am concerned, Emacs will probably be the biggest hurdle for most people not used to it.
Can I use VS Code? Yes, yes you can, but I am not familiar with setting up a VSCode dev environment for Emacs, or any other environment hat comes close to the live environment that emacs provides for this?
Why the fuck should I try Common Lisp or any Lisp for that matter? You do not have to, I happen to like it a lot and have built applications at work with a different dialect of Lisp known as Clojure which runs in the JVM, do I recommend it? Yeah I do, I love functional programming, Clojure is pretty pure on that (not haskell level imo though, but I am not using Haskell for anything other than academic purposes) and with clojure you get the entire repertoire of Java libraries at your disposal. Moving to Clojure was cake coming from Common Lisp.
Why Common Lisp then if you used Clojure in prod? Mostly historical reasons, I want to just let people know that ANSI Common Lisp has a lot of good things going for it, I selected Clojure since I already knew what I needed from the JVM, and parallelism and concurrency are baked into Clojure, which was a priority. While I could have done the same thing in Common Lisp, I wanted to turn in a deliverable as quickly as possible rather than building the entire thing by myself which would have taken longer (had one week)
Am I getting something out of learning Common Lisp? Depends on you, I am not bringing about the whole "it opens your mind" deal with Lisp dialects as most other people do inside of the community, although I did experience new perspectives as to what programming and a programming language could do, and had fun doing it, maybe you will as well.
Does Lisp stands for Lots of Irritating Superfluous Parentheses or Los in stupid parentheses? Yes, also for Lost of Insidious Silly Parentheses and Lisp is Perfect, use paredit (comes with Portacle) also, Lisp stands for Lisp Is Perfect. None of that List Processing bs, any other definition will do.
Are there any other books? Yes, the famous online text Practical Common Lisp can be easily read online for free, I would recommend the Lisperati tutorial first to get a feel for it since PCL demands more tedious study. There is also Common Lisp a gentle introduction. If you want to go the Clojure route try Clojure for the brave and true.
What about Scheme and the Structure and Interpretation of Computer Programs? Too academic for my taste, and if in Common Lisp you have to do a lot of things on your own, Scheme is a whole other beast. Simple and beautiful really, but I go for practical in terms of Lisp, thus I prefer Common Lisp.
how did you start with Lisp?
I was stupid and thought I should start with it after a failed attempt at learning C++, then Java, and then Javascript when I started programming years ago. I was overwhelmed, but I continued. Then I moved to other things. But always kept Common Lisp close to heart. I am also heavy into A.I, Lisp has a history there and it is used in a lot of new and sort of unknown projects dealing with Knowledge Reasoning and representation. It is also Alien tech that contains many things that just seem super interesting to me such as treating code as data and data as code (back-quoting, macros etc)
I need some inspiration man......show me something? Sure, look for a game called Kandria in youtube, the creator, Shimera (Nicolas Hafner) is an absolute genius in the world of Lisp and a true inspiration. He coded the game in Common Lisp, he is also the person behind portacle. If that were not enough, he might very well also be Shirakumo, another prominent member of the Common Lisp Community.
Ok, you got me, what is the first thing in common lisp that I should try after I install the portacle environment? go to the repl and evaluate this:
(+ 0.1 0.2)
Watch in awe at what you get.
In the truest and original sense of the phrase (MIT based) "happy hacking!"10 -
If I could, I'd attempt to create an ideal language. I'd aspire that its features would be:
-The easyiness of Python
-The library ecosystem of Javascript
-The readability and cross- platformness of Java
-Functional features of Haskell
-Modularity of Lisp
-Low level features of C/C++
-Powerful with strings and data, like Perl
-Both compiled and interpreted, with REPL
Anything missing from your favorite languages?9 -
Testing a script embed plugin I am building on various random websites, and came across this.
Like, bruh; have you ever heard of a javascript map? Basic functional programming? Or even a switch statement?
It's the same statement, over and over again, but with different parameters. Even old javascript had enough tools to do this with at least a basic stench of "efficiency"

Should I learn Haskell? Would it help me with other coding languages as well?

Okay, we must first establish common ground here. What do we understand about "showing"? I understand you probably mean displaying/rendering, more abstractly: "obtaining". Good, now we move on.
What's the point of a front-end? Well, in the 90's that used to be an easy answer: to share information (not even in a user-friendly way, per se). Web 2.0 comes, interaction with the website. Uh-oh, suddenly we have to start minding the user. Web 3.0 comes, ouch, now the front-end is a mini-backend. Even tougher, more leaks etc. The ARPAnet was a solution, a front-end that they had built in order to facilitate research document-sharing between universities. Later, it became the inter(national) net(work).
First there was SGML to structure the data (it's a way of making it 'pretty' in a lexicographical way) and turn it into information (which is what information is: data with added semantics) and later there was HTML to structure it even further, yet we all know that its function was not prettification, but rather structure. Later came CSS, to make it pretty. With its growing popularity, the web started to be used as a publishing device.

If we are to solely display JSON data in a pretty way, we may be limiting ourselves to the scenario of rendering pretty web pages using aesthetic languages such as CSS. We must also understand that if we are only focusing on making a website pretty with little to moderate functionality, we aren't really winning. A good website has to be a winner in all aspects, which is why frameworks came into existence, but.. lmao, let's leave that to another discussion.
Now let me recall back my college days.. front-end.. front-end.. heck, even a headset can be a front-end to a pick-order backend. We must think back to the essence, to the abstract. All other things are just implementations of it (yes, the horrendous thousands of Javascript libraries, lol).
So, my college notes say:
"Presentation layer: this is the UI.
In this layer you ask the middle tier for information, which gets that information from a database, which then goes back to middle tier, back to presentation. In the case of the headset, the operators can confirm an order is ready. This is essentially the presentation tier again: you're getting information from the middle tier and 'presenting it' as it were.
The presentation layer is in essence the question: how do I bring my application data to my end users in a platform-and solution-independent way?"
What's JSON? A way to transport data between the middle tier and the presentation tier. Is that what frontend development is? Displaying it in a pretty way? I don't think it is, because 'pretty' is an extra feature of obtaining and displaying data. Do we always have to display data in a pretty way? Not necessarily. We could write a front-end script (in NodeJS perhaps) that periodically fetches certain information from a middle-tier is serves a more functional role rather than a rendering one.
The prettification of data was a historical consequence of the popularity of the web (which is a front-end) (see second paragraph with link). Since the essence of a front-end is to obtain information from the back-end (with stress on obtaining), its presentation is not necessarily a defining characteristic of it, but rather an optional and solution-dependent aspect, a facet.4 -
Starting to get into intricacies of javascript.
Question was: when and why do you bind your functions?
Farking hell， no wonder people bitch about javascript.3 -
MORE WEBDEV ADVENTURES
Took a break for a while due to personal stuff. Just got a job (have to get a stupid work permit from school first to actually be able to work tho), had some shit happen with two close friends that now hate me. Right now I'm upset about something that another really good friend did. So I've been doing some webdev to distract myself for a bit.
So I'm turning my URL bar that I had into a little command bar. It'll be what I use to configure stuff along with URLS and shit. I was building a little config menu that I really hated doing, was just becoming too much of a mess. Currently changing the look of it just a bit, then I'm gonna work on the functionality of it later.
Made my weather divs dynamically generated. Turned like 65 lines in the HTML file to ~20 lines of JavaScript that makes that ~65 lines. And it turns out that it doesn't really affect the loading time at all, which was my original worry. My next task for that is to save the weather predictions so the script doesn't have to grab a whole 14kb file every reload (I know, that part's a little bad). The entire page with the icons and all comes out to ~30kb so far. The icons make up about half of that, but they'll never all be in use because only 5 are on screen at any time and there are 7 total. Plus the fact that one may be in use multiple times (like this very moment actually).
Then I want to have an RSS reader which I've been putting off for a while now. Trying to get everything else done before I do that.
At this very moment, the page takes about 1.4 seconds to load. I'm trying to avoid putting anything I don't need in it. Like I'm using vanilla everything. No frameworks or anything. But that's just my personal preference.
I'll make sure to share it with you guys when I have everything built and functional. I've had a lot of interruptions while doing this. My personal life tends to get in the way of shit I try to do, because I let it get to me.
Anyways I'm just rambling at this point. I fucking love you guys1 -
Functional programming, Reacts! Because that's what the cool kids are using now... nice rant https://hackernoon.com/how-it-feels...

What's your opinion on functional shortcuts and 'hacks' in many languages, like map/reduce/filter, ternary operator, lambdas,inner/anonymous classes?
Imo they can make development faster and more efficent but they make the code very unreadable, especially if someone else has to read it, Therefore I try to use them only when it's appropriate. My dev friends use them too much and it makes reading their code a hellish experience, especially in Javascript with Rx.3 -
Finding it hard to focus. I'm into UI, backend, frontend, iOS... Exploring FP. We've just had our first child and I need to put my time and energy into what will a) provide healthy financial remuneration b) be more enjoyable than frustrating c) be relatively futureproof (if that's even possible). For some reason I have a huge distaste for JavaScript (as an ecosystem) which has led me to look into Elm. I've enjoyed Ruby but something in my mind tells me Functional programming is more logical for me. It's a whole new approach and skill to level-up on. I love programming my own back-ends, but for me, design is so important and I want to be part of the visual, tangible part that people interact with. I'm a one-man operation which means I do design, full stack Development, client liaison, financials, client acquisition. Freelancing is a double edged sword - I don't know when the next project will come, but I also need to focus on the projects I have without taking too much on. At times I think employment would be good, despite having it's on drawbacks which I read about repeatedly on here. Any advice?1

For those with hiring experience, or just informed opinions.
Candidate A:
1.5 years self-taught web development, primarily Javascript, but also Ruby & Golang
6 months commercial front end experience
Brucey Bonus: a significant fullstack personal project (deployed), plus lots of smaller projects. Has focused a lot on learning OOP and functional paradigm principles.
Candidate B:
As candidate A, but instead of a personal project, has made a couple dozen PRs on a big open source project (ie Mozilla’s debugger). They seem to have eschewed really dialling down into algorithms/paradigms, preferring to learn “in the wild”.
They both perform equally well in interview tests, and appear to be engaging, hardworking and approachable.
Which one do you pick, and why?24 -
A colleague of mine said that functional programming should be banned by law. He finds it so hard and at the same time the only language he knows is JavaScript

No matter how many times I have to rewrite functional code, no one will ever convince me that dynamically creating JavaScript with data binding templating languages is a good idea (JSP, php, etc)3

Modern Web Developer
(To the tune of "I Am the Very Model of a Modern Major-General" from Gilbert and Sullivan's "The Pirates of Penzance")
I am the very model of a modern web developer
I’m quite fluent with JavaScript; An HTML whisperer
My code is clean and elegant, I genuinely innovate
And even know my way around a Promise and async / await
I’m very well acquainted too with matters vector graphical
I understand why SVG coordinates seem magical
And even without Photoshop I elegantly can produce
A mockup or a logo in most any format that you choose
[Chorus]
A mockup or a logo in most any format that you choose
A mockup or a logo in most any format that you choose
A mockup or a logo in most any format that you choose
I'm quite adept at ES6 expressions like destructuring
I know the ins and outs of functional reactive programming
In short, in matters browser-based or Node.js if you prefer
I am the very model of a modern web developer
[Chorus]
He is the very model of a modern web developer
I know our mythic history, the humble start, the browser wars
I know why Douglas Crockford fought the battle over ES4
The World Wide Web Consortium and Ecma International
My knowledge of our legacy is truly supernatural
With LESS and SASS and CSS, designing for mobility
I’ll perfectly apply the right amount of specificity
From custom fonts and parallax to grid and flex and border-box
I know most every tip and trick both common and unorthodox
[Chorus]
He knows most every tip and trick both common and unorthodox
He knows most every tip and trick both common and unorthodox
He knows most every tip and trick both common and unorthodox
And when it comes to lazy loading, bundling up and splitting code
There’s nothing quite like Webpack, which of course is built on top of Node
Considering my resume, I’m certain that you will concur
I am the very model of a modern web developer
[Chorus]
He is the very model of a modern web developer
When new frameworks and libraries emerge I must be ravenous
And gobble up the hot new thing, my appetite is bottomless
React and Vue and Angular, Immutable, RxJS
The list will be outdated long before I'm finished singing this
My pull requests rely on multitudinous utilities
To help me lint and test and build, a deluge of analyses
And every single day there are a hundred thousand more to learn
The web is going through an irresponsible amount of churn
[Chorus]
The web is going through an irresponsible amount of churn
The web is going through an irresponsible amount of churn
The web is going through an irresponsible amount of churn
This pace is agonizing! Code from yesterday is obsolete!
The speed of innovation is enough to knock me off my feet!
It's happening too fast! I can’t keep up! I’m tired! It’s all a blur!
I am the very model of a modern web developer!
[Chorus]
He is the very model of a modern web developer!1 -

Help me out a bit, functional programming fans!
I'm experimenting with functional programming through JavaScript.
I created some dummy data to experiment with and created a simple function to query the data. I would like to get all elements, whose type attribute is not 'x'. A simple solution can be seen under the 'original code' part.
Under the 'fully functional code' part I gathered some frequently used general purpose functions, which I assembled into the function composition at line 45.
I'm having a bad taste in my mouth and feel that I've gone too far. I basically replaced every language element for a function. Is this the goal of functional programming? Is this how a perfectly functional code should look like?

Sometimes I think that TypeScript is like a poor developer's Haskell. I thought "Isn't this supposed to support functional programming?" and searched for a way to do currying or partial application, and only found hackish solutions :/ Then again, maybe I don't know Haskell well enough to make a proper judgment.1

Why in the hell does everyone have to have a different fucking CMS and why do they all make it so goddamn difficult to put a simple javascript in the head?
it's 2016 fuckers, sometimes the end user hires a dev to do things and I can't do shit in your fucking site-builder. I want to add a tiny javascript specifically for fb pixel, but frankly this is how most analytics work and it shouldn't be a complicated task for someone to perform if you built a halfway functional fucking CMS.
One simple function is all it would take to let users put a little bit of js in the head, fuck you could even name it something scary to keep idiots away or hide it behind a developers options in the settings or something that would allow someone with the IQ of a dolphin or higher to install some goddamn tracking code on the fucking shitstorm of a site your "builder" came up with.
your SEO practices suck too, but that's a rant for another time2 -
After weeks of agonizing and cursing Electron JS and JavaScript......
I finally managed to get all my modules to sync up and play nice with each other!
Love JavaScript again! Although seriously had enough issues with asynchronous tasks and threads.
Heading over to the dark side(functional) now.... 😈😈
