Friend: dude, JavaScript seems awesome. It looks so easy and there aren't any annoying compiler errors like in Java

Me: I know it sounds cool in theory, but it sucks in practice, trust me

Friend: no way, dynamically typed languages are the future

*Friend installs node*
*Friend writes a simple script*
*Friend gets undefined errors because of a few typos and has a hard time debugging it*

Friend: JavaScript is retarded

-_-

This never happens with statically typed languages

Dynamically typed languages are barbaric to me.

It's pretty much universally understood that programmers program with types in mind (if you have a method that takes a name, it's a string. You don't want a name that's an integer).

Even it you don't like the verbosity of type annotations, that's fine. It adds maybe seconds of time to type, which is neglible in my opinion, but it's a discussion to be had.

If that's the case, use Crystal. It's statically typed, and no type annotations are required (it looks nearly identical to Ruby).

So many errors are fixed by static typing and compilers. I know a person who migrated most of the Python std library to Haskell and found typing errors in it. *In their standard library*. If the developers of Python can't be trusted to avoid simple typing errors with all their unit tests, how can anyone?

Plus, even if unit testing universally guarded against typing errors, why would you prefer that? It takes far less time to add a type annotation (and even less time to write nothing in Crystal), and you get the benefit of knowing types at compile time.

I've had some super weird type experiences in Ruby. You can mock out the return of the type check to be what you want. I've been unit testing in Ruby before, tried mocking a method on a type, didn't work as I expected. Checked the type, it lines up.

Turns out, nested away in some obscure place was a factory that was generating types and masking them as different types because we figured "since it responds to all the same methods, it's practically the same type right?", but not in the unit test. Took 45 minutes on my time when it could've taken ~0 seconds in a statically typed language.

Am I the only one who, when working with dynamically typed languages, never uses dynamic features? Like, I never change a variable type, and make sure functions will only return one data type?
I just think dynamic types leads to so many bugs

Python. Ok, so it's a really cool language, as a scripting language it's awesome, quick to write.

When it's been used to make full fledged oop programs that you suddenly have to maintain things like duck typing become problematic. Looking at an object fuck knows what methods are available. Worse still when some bastard that thinks he's being clever doesn't bother declaring any object attributes and instead overrides the __set_attr method to dynamically add them as they are used there is no hope for the poor sod that has to maintain it later.

I've also now worked out I'm at least the 3rd person having been given the task of maintaining it, i spent a day changing CLI options wondering why they didn't do anything but occasionally crash the app. I've now found a few thousand lines deep that someone had hard-coded these values because they couldn't work out where to get the CLI args from!

I've gained a new appreciation for nominative, strictly typed languages.

A dynamically typed scripting language written in Go

I'm a long time Unity3D C# programmer and i mostly build android games for fun. About half a year ago i dumped windows for Debian Linux(fucking love it) but I quickly started to miss my unity3d environment. Unity in a VM doesn't work and the outdated, beta, crash prone linux version doesn't support android so i started looking for an alternative.

I decided to give Godot a shot but moving from a statistically typed language to a dynamically typed one literally breaks my brain. The last couple of hours of reading the documentation pretty much consisted of: WHAT? YOU CAN'T DO THAT! NO. WHAT? WTF IS THAT SYNTAX? oh I think I'm getting it WHAT DO YOU MEAN POINTERS DON'T EXIST!?

One of the most infuriating ideas in software development culture is that you can build maintainable applications without a strictly enforced type system and structured data.

Sure, it's more fun to wack around a dynamically typed system until it works or to write a major application with mutable datastructures... It's a least fun until a few years in and you have to debug an unexpected overwrite or a inconsistent use of an object property or whatever.

Anyone who writes maintainable code eventually figures out that you need rules and procedures, the issue with JavaScript, python, ruby, lisp, etc developers is that they think it's us developers that needs to enforce these rules instead of the compiler (which is infinitely better at it).

Dynamically typed languages suck. God I hate them

It's like one big clunky free for all. I don't understand how people can work in Python or even JavaScript and tell me that they're good languages with a straight face

Not having proper autocomplete or documentation (a somewhat seperate issue of Python) is a kick in the stomach for productivity.
I've seen people advocate for using EXTERNAL DOCUMENTATION VIEWERS. WHAT

I hate not being able to enforce types so I can reason about little parts of my program. I hate not having an IDE that can actually help me. I hate having to see stupid grep'ed code snippets instead of nicely formatted javadocs. I hate having to double and triple check everything when trying to code. I hate handling effectively opaque values where I don't know anything about the type without looking it up. And I especially hate not knowing what types function parameters need to be.

Dynamic typing doesn't remove types. That, although completely unfeasible, I could respect.
Oh no, the types are still there. Just not for you

It's like solving a jigsaw puzzle with a blindfold on

You know what really grinds my gears? When people criticize a programming language but uses edge cases and stuff that can be avoided by using the tried and true "don't be an idiot". Take for instance JavaScript, a language I like and a language that has a lot you can criticize. But I feel like a lot of peoples criticism isn't warranted.

What's that? No ints? Use parseInt or Math.floor.

What are you saying? == works in strange ways? Yes, that's what we have === for.

Type coercion is wonky? Think it's weird how string + int works differently than string - int? Wanna string with number + - + - - + - - etc? Don't! Don't add strings and ints, don't subtract strings and ints. You can't in statically typed languages and you aren't supposed to in dynamically typed

Adding arrays and objects, arrays and arrays, objects and objects etc. is inconsistent? Why are you trying to do that?

Adding floats together gives odd results? Now we're getting somewhere! And Mozilla responded to that with a method called toFixed.

Declaring variables with var doesn't always work that well? Use let and const

Then there's this weird attitude that some people I've met have, where they will complain about the module system and how "well you rely on the community for those packages" as if it's a bad thing. And then coming with the "well you don't know what the (open source) packages do internally" as if I (for the most part) give a shit. Then they'll swear by companies like Zend or Microsoft as if they can't just stop supporting the languages they use. Maybe it's just because I like community content more because of video game mods.

Wanna criticize JS, then there's plenty to talk about. Like the built in date object is basically shit. Or how in NodeJS you can have node_modules in your node_modules. Or how classes don't really have the best syntax. Left-Pad. And so on (it's too late for me to be able to remember much more).

Why would anybody use dynamically typed languages? I mean it is lot safer to use static languages, no? No weird bugs, no weird outputs...

How they manage to write such big applications in dynamical languages?

Stop. Using. Fucking. ADA. To. Teach. Basic. Programming.

I wouldn't say you should use a dynamically typed language like Python, but having programed since high school, I hated each and every aspect of Ada. We were even taught OOP and generics with it! (And not, you do not want to know how it is, because it is dreadful)

Today's rant: JavaScript's type system.

I realized halfway through that I can't happily call JavaScript a "programming language" so just assume
alias programming="scripting"

I'm sure it's not actually as frustrating as it seems to me. Thing is, I'm used to either statically-typed languages or dynamically-typed languages that actually make sense. If I were to try to add an integer to something I'd forgotten was a string in Python, it'd immediately tell me "look, buddy, do you want me to treat this as a concatenation or an addition? I have no idea the way you've got this written." I've found that mistakes are a common thing with dynamic typing. Maybe I'm just not experienced enough yet, maybe it's really as stupid as it looks. JavaScript just goes "hey look I'm gonna tack all of these guys together and make a weird franken-string like '$NaN34.$&' because that's absolutely what we want here!" Then I run my webpage and instead of a nice numeric total like I wanted, good old JavaScript just went "Yep, I have no idea what I'm doing here I'm just gonna drop this here and pretend it's right." Now absolutely I do not expect my programming language to make correct assumptions and read my mind, otherwise JavaScript would be programming me and not the other way around. But it could at least let me know that I had incompatible types going on rather than just shamelessly going along with what it's doing. Good GRIEF, man, some of the idiosyncrasies of the EMCAScript language definition itself just make me want to punch a horse.

I am a computer science student and have worked with Java and C++ until now. A week ago i started in a job i have gotten from my professor. I have to reverse engineer a big python project and figure out how some things work on the serverside. This is the first time i have to work with python.

I get that you can write code fast with this dynamically typed language, but BOY. Is it just me or is this language fucking hard to reverse engineer? I mean what the fuck. There are some member variables in which can be anything. Like you suggest there is an object of this and that and then python comes in and is like: Good guess, but fuck you.

Python. Oh dear Python. Why, oh why, when I have your function with parameters defined as an int, do you blithely accept a string and just go about your merry day? If I wanted you to be able to accept a string I would have let you accept a string. But no, I want ints. Its not a suggestion. Its a demand.

You're dynamically-typed thug life gets on my static-typed backgrounds nerves.

(I am fully aware of the reasons for it and why, but my goodness I do sometimes miss my static-typed compile error languages, rather than pseudocode that accidently compiles python)

Can someone please tell me what is so attractive about a dynamically typed language? It's not like it makes anyone's life easier – it just leads to more unexpected errors.

I find dynamically typed language a lot easier to read and understand than statically typed language.

What's up with all these interfaces, types and abstractions, its just too much!

I do want structure when writing code, but also the flexibility to test things without the f*** interface/type errors!!!

Bro typescript is sooooooo gooood...
holy shit!
coming from a cpp/java background it feels like a fucking relief to know something like typescript exists and you dont have to blindly trust the dynamically typed crap

Some times I get these weird ideas.

The machines now rule the world and they decided humans will not be able to program them anymore. That's why they enslaved you as part of the committee which will create the next computer language: Cryptic Script.

What feature would you add to it?
(try something real)

I'll starting by saying Cryptic Script is dynamically typed.

Hi, in my JS project I have to update a variable value that is getting a text input's value in order to use it dynamically with different functions across my program. What would be the best approach to doing this?

Should I make a function that updates the variable for every character typed or should I simply get the value when the function is called?

Thanks!
