Search - "ecmascript"
- Sure! What do you need?
Oh, it’s very simple, I just want to make a static webpage that shows a clock with the real time.
- Wait, why static? Why not dynamic?
I don’t know, I guess it’ll be easier.
- Well, maybe, but that’s boring, and if that’s boring you are not going to put in time, and if you’re not going to put in time, it’s going to be harder; so it’s better to start with something harder in order to make it easier.
You know that doesn’t make sense right?
Okay, so I want to parse this date first to make the clock be universal for all the regions.
- You’re not going to do that by yourself right? You know what they say, don’t repeat yourself!
But it’s just two lines.
- Don’t reinvent the wheel!
- One component per file!
- It happens, and you’ll get lost managing your files as well. You should use Webpack or Browserify for managing your modules.
- Yes, but some people still have previous versions of ECMAScript, so it wouldn’t be compatible.
Why is it called ECMAScript then?
- It’s called both ways. Anyways, after you install Webpack to manage your modules, you still need a module and dependency manager, such as bower, or node package manager or yarn.
What does that have to do with my page?
- So you can install AngularJS.
Oh, that’s great, so if I modify one sentence on a part of the page, it will automatically refresh the other part of the page which is related to the first one and viceversa?
- Exactly! Except two way data binding is not recommended, since you don’t want child components to edit the parent components of your app.
Then why make two way data binding in the first place?
- It’s backed up by Google. You just don’t get it do you?
I have installed AngularJS now, but it seems I have to redefine something called a... directive?
- AngularJS is old now, you should start using Angular, aka Angular 2.
But it’s the same name... wtf! Only 3 minutes have passed since we started talking, how are they in Angular 2 already?
- You mean 3.
Okay, I now know Angular 6.0, and use a component based architecture using only a one way data binding, I have read and started using the Design Patterns already described to solve my problem without reinventing the wheel using libraries such as lodash and D3 for a world map visualization of my clock as well as moment to parse the dates correctly. I also used ECMAScript 6 with Babel to secure backwards compatibility.
- That’s good.
- But did you use TypeScript?37
Recently i had to interview a guy with 10 years of frontend experience for a react developer role
Me : Do you know what ecmascript is ?
Him : Yes
Me : Which version would you prefer to use and why ?
Me : (totally confused) 😶
Me : (Trying hard to not "react") Ok.
How would you "react" to this ?31
Okay, story time.
This rant is about the many mistakes I made at the time, specifically the biggest – but not the first – of which: publishing some preliminary results very early on.
So I posted a sarcastic question to the Software Engineering Stack Exchange, which was originally worded differently to reflect my frustration, but was later edited by mods to be more serious.
You can see the responses for yourself here: https://goo.gl/poHKpK
Most of the serious answers were along the lines of "multithreading is hard". The top voted response started with this statement: "1) Multithreading is extremely hard, and unfortunately the way you've presented this idea so far implies you're severely underestimating how hard it is."
While I'll admit that my presentation was initially lacking, I later made an entire page to explain the synchronisation mechanism in place, and you can read more about it here, if you're interested:
But what really shocked me was that I had never understood the mindset that all the naysayers adopted until I read that response.
Because the bottom-line of that entire response is an argument: an argument against change.
Nexus does not and will not hold your hand. It will not repeat Node's mistakes and give you nice ways to shoot yourself in the foot later, like `process.on('uncaughtException', ...)` for a catch-all global error handling solution.
No, an uncaught exception will be dealt with like any other self-respecting language: by not ignoring the problem and pretending it doesn't exist. If you write bad code, your program will crash, and you can't rectify a bug in your code by ignoring its presence entirely and using duct tape to scrape something together.
Back on the topic of multithreading, though. Multithreading is known to be hard, that's true. But how do you deal with a difficult solution? You simplify it and break it down, not just disregard it completely; because multithreading has its great advantages, too.
Like, how about we talk performance?
How about distributed algorithms that don't waste 40% of their computing power on agent communication and pointless overhead (like the serialisation/deserialisation of messages across the execution boundary for every single call)?
How about vertical scaling without forking the entire address space (and thus multiplying your application's memory consumption by the number of cores you wish to use)?
Some will say that the performance gains aren't worth the risk. That the possibility of race conditions and deadlocks aren't worth it.
That's the point of cooperative multithreading. It is a way to smartly work around these issues.
If you use promises, they will execute in parallel, to the best of the scheduler's abilities, and if you chain them then they will run consecutively as planned according to their dependency graph.
If your code doesn't access global variables or shared closure variables, or your promises only deal with their provided inputs without side-effects, then no contention will *ever* occur.
If you only read and never modify globals, no contention will ever occur.
Are you seeing the same trend I'm seeing?
When someone says we shouldn't use multithreading because it's hard, do you know what I like to say to that?
"To multithread, you need a pair."18
Why the hell does every single frontend job on Earth require expert knowledge of React, a fad JS library that will be forgotten in 5 years?
Look, I understand the appeal of separating code into repeatable components. I just don't understand why essentially the same thing can't be accomplished with vanilla JS, which is ten times easier to understand and doesn't require an entire website to be written in some make-believe offshoot of Ecmascript that will look like hieroglyphics a decade from now.
Sometimes I see advice given to others that is either clearly wrong or even dangerous, but it's not socially acceptable to call them out on it because 'everyone is entitled to their opinion'.
Yes, you're right. I'm entitled to my opinion based on doing this for 20 years and facing your exact, usually "junior" situation a hundred times. You did a code camp earlier this year and still think JSX is part of the Ecmascript standard.
There is a difference, and not being able to point it out without being scolded for being "entitled" (ironically) is slowly draining me of any interest in helping others.
How the fuck do you cope with this?18
Just found out that IE11 doesn't even support ES6 classes...
I couldn't care less about but still...6
Well done firefox for not implementing some stuff from ES6, because you decided to do so. Isn't the releases of EcmaScript considered to be standards? I'm a Firefox fan, but damn, Chrome is so much more advanced.7
Fuck the new ECMAScript 2018 specifications.
I mean seriously? How the hell is dot syntax gonna make it more readable?
Also, i love the brackets, braces and semicolon. Hate to see them deprecated.
Almost gave me a heart attack and my head was boiling watching it.
It's official, the "front end dev" doesn't know how to code.
And it's not a "Well I don't know JS because I use React." scenario, no. He has almost no idea of coding.
What was he thinking trying to build the front end of a very complex app with just HTML, CSS and stupid copied and pasted snippets?5
What was the most stupid thing interview ever do to you?
(Isn't ecmascript or something?)
I have multiple (in no particular order) :
Nextcloud : It was an idea that I had in my head as well - to take on corporations like Google in the space of personal cloud. Be free, open-source and put the users in charge.
Gitlab : The most open and transparent company that I've ever come across. And they work 99% remote. They've got features that no other players in the space have. All while putting users in control.
Fediverse social media - Mastodon, GNU Social, Diaspora (soon) : For taking a major step in the direction of putting the users in control of their data; all while enabling a decentralized social network.
Ruby : An open community and building a programming language that runs a lot of software of the world.
Python : The oldest thriving community that has a special place in the development community (and my heart)
ECMAScript is everywhere, so I thought: Let's do even more inappropriate and insane things with it ;)
...Like using Duktape (small ECMAScript engine) and exposing LoadLibrary/GetProcAddress along with some helper routines to describe the routine's argument types and return type, and finally providing a routine to invoke those routines.
It's a very rough prototype that can handle up to 4 arguments in a 64-bit Windows environment.
Next "todo" is structure handling which will initially be a case of stuffing data into a Buffer() object.
I'm not sure what exactly I'm trying to do with it or why...1
I wish I could redesign the webstack. I mean, its fine in its current state, but could be soooo much better.
Having native support for web components and shadowDOM will be a good start.
Crossbrowser support for flexbox and removal of vendor prefixes.
CSS defaults for properties like margin and padding to be set to 0. (Basically reset.css or normalize.css)
I like the direction ECMAscript is heading in but I think some features that Dart has should also be ported ECMAscript. The simplified DOM in dart which looks like jQuery is such a breeze to use.
We can all the above currently, but its integration would streamline development.4
I like there's a new ECMAScript version but ECMAScript 2015 didn't replace ECMAScript 5 as BrowserJS
huh the more you know
Oh, the SORROW that is JEST! 😡
Endless days have been swallowed by the abyss in my quest to configure Jest with TypeScript and ECMAScript modules instead of CommonJS. Triumph seemed within my grasp until - BAM! - suddenly the tool forgets what "import" or "export" means. And the kicker? On the CI, it still runs like nothing’s amiss!
Allow me to elucidate for the uninitiated: Jest is supposed to be a testing safeguard, a protective barrier insulating devs from the errors of their peers, ensuring a smooth, uninterrupted coding experience.
But OH, how the tables have turned when the very shield becomes the sword, stabbing me with countless, infuriating errors birthed from Jest’s own design decisions!
The audacity to reinvent the whole module loading process just to facilitate module mocking is mind-boggling! Imagine constructing an entirely new ecosystem just to allow people to pretend modules are something they're not. This is not just overkill; it's a preposterous reinvention of a wheel that insists on being a pentagon!
Sure, if devs want to globally expose their variables, entwining everything in a static context, so be it. BUT, why should we, who walk the righteous path of dependency injection, be subjugated to this configured chaos?!
My blood boils as the jestering Jest thrusts upon me a fragile, perpetually breaking system, punishing ME for its determination to support whole module mocking! A technique, mind you, that I wouldn’t touch with a ten-foot pole, because, you know, DEPENDENCY INJECTION!
Where are the alternatives, you ask? Drowned in the abyss, it seems! Why can’t we embrace snapshots and all the delectable integrations WITHOUT being dragged through this module-mocking mire? Can’t module mocking just be a friendly sidekick, an OPTIONAL add-on, rather than the cruel dictator forcing its agenda upon our code?
Punish those clinging to their static contexts, their global variables – NOT those of us advocating for cleaner, more stable practices!
It’s high time we decouple the goodness of Jest from its built-in bad practices. Must we continue to dance with the devil to delight in the depth of Jest’s capabilities?
WHY, Jest, WHY?! 😭9
(at least for me as a non-js dev)

Got a new job. Its all good. Fun work, great colleagues and good pay. However, last week they mandated some new surveillance tech so all network traffic is unencrypted, logged, stored and analyzed.
Should I stay or should I go? I am big into privacy. What would you do?27
I spent half of the day trying to make the Grunt script of my node project which uses ECMAscript 6 (Harmony) and make compatible with Uglify-JS by using Babel... Then I found there was a branch of Uglify-JS for Harmony and I only had to update my dependency which took me 2min -_-
1) what do i have to know to be a good react native developer?
3) how hard is typescript/ecmascript and what do i need to know to understand it? only js i guess or something else?
5) tips for learning react native as fast and as efficiently as humanly possible
ECMAScript was not the first non-Schemey language implemented by Guile, but it was
the first implemented for Guile’s bytecode compiler. The goal was to support ECMAScript version 3.1, a relatively small language, but the implementor was completely irresponsible and got distracted by other things before finishing the standard library, and even some bits of the
syntax. So, ECMAScript does deserve a mention in the manual, but it doesn’t deserve an endorsement until its implementation is completed,
perhaps by some more responsible hacke2
Any SUPER AWESOME patient... JS PRO that wants to help me with a few problems it would be appreciated..
> I don't know how to learn without mimicking what the person is doing and when I try something that's related I cant use the related information and techniques because I either don't remember, dont want to do the literal same thing for something slightly different or dont know how and somethings not working even though it should be.
> I do it one way and when people offer to help its just me getting responses of how it could be done completely different and I dont understand why either way should be used
> Why should I have to generate a webpage or div if I can just use HTML5
>whats the difference between JSON and Arrays???????????
>I am not good with arrays, lists, dictionaries, (I'm stretching to python with lists and dictionaries)
>I recently tried the basic quiz project and it was more complicated and fun than I was giving credit for but I want to do it a different way to show myself I learned but I cant because I dont understand how the person managed to loop through the entire array printing the individual questions and answers to the div. like I understand the parts that use the html tags in the code but I dont know how when or what to use it all
At this point Im just stressing because all I want is a basic skillset with JS but I dont feel like Im learning anything and I dont know how to apply my knowledge or improve upon the programs ive been learning from or trying to make. and arrays have been tripping me up to especially since I have no clue what the difference is between them and JSON and why I should use one over the other and dont get me started how shit I am with manipulating them. FUCK IM STUPID10
Looking through ecmascript documentation and im not recognizong anything under the arrays.
Oh thats the ruby documentation. Why am i on the ruby documentation
Dear web developers, please think of the boot disk users.
Users might have to boot their computer from external bootable media such as a live USB stick, SSD, or live CD/DVD, after their operating system caught a problem that prevents it from booting.
Emergency boot media usually has earlier versions of web browsers because they are not frequently used, much less updated. Sadly, the developers of many websites have a habit of breaking compatibility for older web browsers. For example, the new audio player used by the Internet Archive (Archive.org) does not even support Firefox 57, a version that was released as recently as November 2017!
Therefore, websites should retain support for old web browsers. If not all features can be made to work, at least the essential features should work on older browser versions. Websites should not let down people who are stuck due to a computer problem. Those users should still be able to browse the Internet for help, and perhaps enjoy basic entertainment such as watching videos (YouTube, Dailymotion) and listenening to music or audio books (SoundCloud, Internet Archive) while at it.
The attached screenshot shows something no internet user wants to be "greeted" with.
Keep the Internet accessible.21
Are we really asking too much for someone interested in a temp role or are we just getting unqualified candidates?9
I write code as part of my job but also tend to have a lot of pet projects I think about in my spare time. A lot of those projects are not specifically targeted at solving an actual real problem but are just a curiosity (like my Duktape/ECMAScript thing that could import and call DLL routines.) I often find it difficult to choose which one to continue working on and end up not working on any of them because I can't decide which one is more interesting at the time! Or I get stuck and struggle to find a way around whatever roadblock I've hit.1
started out with react.....its been a fucking week hopping from documentation to youtube to udemy, edx, pluralsight, blogs and what not..... All hit me at once: babel, webpack, ecmascript, fuckin hell.... Cant even set up my machine on my own without any boilerplate to just start working with a fucking framework ..... Uughhh!! Finally found a setup guide on scotch.io.... Followed the steps using yarn(as thats what the tutorial creater used). Worked flawlessly. Tried to imitate using npm, doesn't work.... Why? Fucking piece of crap framework... Steep learning curve..... Cool logo tho.2
TIL ECMAScript (2015) supports tail call optimization, except virtually only safari can do that, making it useless1
Is ECMAScript a dialect of Lisp?
— Douglas Crockford
An interesting discussion on SO (https://stackoverflow.com/questions...)2
Read The Docs!!!
Read The Docs!!!
But none of y’all have read the ECMAScript Specification.
Don’t even get me started with W3C… Just stick with your W3Schools5
If I were on the ECMAScript committee, I would just ask them to use python for everything instead.40
ES(afaik)2020 has a new private field declaration proposal feature in classes. I made a gist to try them _when they are implemented properly_.
Gonna test on chrome lolz.
