All your arguments can be applied when comparing ts to js. You can just use the succinct and readable js. Why waste time dealing with this type is implicitly any?

Get things done with js and chill.

Welcome to compiled systems programming languages? What’d you expect?

This entire post is so ignorant it can be summed up in a one paragraph analogy:

“Why do everyone love screwdrivers so much? I drove in nails perfectly with my hammer, but the screwdrivers are so bad at it! Who even designed them? What a horrible design!”

Cargo is doing too many things at once. It’s a build system but also a package manager but also manages dependencies? Idk what to even call it.

Somewhat agreed, but it’s a very difficult problem to solve. No language has yet come up with the perfect build tool. JS is on what, like the 12th build tool in as many years now? Some serious throwing stones in glass houses vibes here.

Syntax is very confusing for no reason. You can’t just look at rust code and immediately know what it does.

Strongly disagree on this point. Those extra glyphs in Rust are not just cosmetic, each one means something very specific and conveys very important information.

Having to pollute your code &, ? and .clone() everywhere to deal with ownership

You don’t “deal with” ownership, it’s an incredibly powerful tool you use. This just sounds like you haven’t really understood what the borrow checker is actually doing and the hundreds of problems it solves for you. I can not count how many times now I’ve been working in another language and had the thought “I could solve this with the borrow checker”

Js is way more readable.

JS is not more readable, JS is just far less detailed. It omits a vast swath of information such that you have almost no idea what it’s actually doing. It feels easier to you because you don’t care about any of the details, but those details become vitally important when things stop working and you’re trying to figure out why. This sounds to me like you’ve never had to write any actually complicated code. If all you’re trying to do is chain together a series of HTTP calls and maybe parse a tiny bit of JSON, yeah, Rust is like using a nuke to kill an ant.

Similarly, Async code starts to look really ugly and overengineered in rust.

A little bit, but mostly because doing async right is really complicated. Once again no language has a really great solution to this problem yet, they all involve tradeoffs.

Multiple string types like &str, String, str, instead of just one “str” function.

Once again it seems you don’t really understand the difference between owned and borrowed values or stack vs. heap allocation and why it matters. Really there’s only one type of String which is String, the others are just different ways of borrowing a String (with different tradeoffs).

i32 i64 i8 f8 f16 f32 instead of a single unified “number” type like in typescript. Even in C you can just write “int” and be done with it

If all you want is a “int” you can just use i64 for everything and “be done with it” as you say, you’ll just be adding a ton of wasted memory and needless overhead for no good reason. Seems like you just don’t like strong typing. I’m surprised you even bother with TypeScript instead of just using JavaScript.

Having to use #[tokio:main] to make the main function async (which should just be inbuilt functionality, btw tokio adds insane bloat to your program) yet you literally can’t write code without it.

You absolutely can write code without using #[tokio:main], you can even use tokio without that, it just saves you having to write a bunch of boilerplate to initialize tokios executer and pass your async functions to it. You can even use async functions without tokio, you just need to provide your own executor. Async in Rust is still pretty new and some of the rough edges are still being worked out, it will get smoother, but honestly the things you’re complaining about aren’t even the annoying parts about it.

Speaking of bloat, a basic get request in a low level language shouldn’t be 32mb, it’s around 16kb with C and libcurl, despite the C program being more lines of code. Why is it so bloated? This makes using rust for serious embedded systems unfeasible and C a much better option.

I have no idea what you’re doing to generate code sizes like that, but I guarantee you could get a significantly smaller program in Rust that does exactly what the C code is doing. As for embedded this is patently false. I personally use Rust regularly on embedded devices that don’t even have 32mb of RAM on them.

With cargo you literally have to compile everything instead of them shipping proper binaries. Why???

This isn’t a cargo thing, this is a Rust compiler thing. The Rust ABI hasn’t been standardized which means currently there’s no guarantee that Rust code compiled by one version of the compiler can successfully link against code compiled by a different version. Until not that long ago C++ actually had the same problem. This will eventually get fixed, but the language team feels things are still moving too fast to define a concrete standard yet.

Another major issue I’ve encountered is libraries in Rust, or lack thereof. Every single library in rust is half-baked.

Rust is still pretty new, so a lot of libraries are still in active development, but there are already many excellent and very well documented libraries. Axum is literally one of the newest web frameworks in Rust and didn’t even exist that long ago. I’ve seen far worse documentation for JS libraries (and don’t even mention C, the gold standard there is practically a man page that’s just a glorified header file).

As for “memory safety”, it’s a buzzword. Just use a garbage collector.

Memory safety is not “just a buzzword”, there’s a reason all the top vulnerabilities for decades now are all memory safety issues. As for a garbage collector, good luck with that when writing embedded software or a kernel.

The rest of your rant basically boils down to “my particular simple use case doesn’t see much value from what Rust provides”, which is fine. If you don’t need the power of Rust, use something weaker, not every problem needs the nuclear option, sometimes you just need something quick and dirty that will run a few times before it falls over. Hell, sometimes a quick Perl script is the right solution. I mean, not often, but it does sometimes happen. When you do find a problem that your quick and dirty approach isn’t working on then you’ll see the value in Rust.

Ok, I’m going to just assume this isn’t a troll.

Cargo is doing too many things at once. It’s a build system but also a package manager but also manages dependencies? Idk what to even call it.

I dont even understand your issue? It’s like npm or deno which can run your code, manage your dependencies, etc. How can a JS/TS dev possibly not understand this?

Syntax is very confusing for no reason. You can’t just look at rust code and immediately know what it does. Having to pollute your code &, ? and .clone() everywhere to deal with ownership, using :: to refer to static methods instead of a “static” keyword. Rust syntax is badly designed compared to most other languages I used. In a massive codebase with tons of functions and moving parts this is unreadable.

I dislike ? because I think you should be handling errors as they come instead of sending them up the stack. I also like the explicit .clone() but if you dont want to use it, you can also add Copy to your derive’s and this will make it happen automatically. module::function() generally pollutes code much less then static module.function() or static function() doesn’t it?

Let’s take a look at hashmaps vs json

I hate all of this code, why arent you using struct’s here? In rust its: struct Person {name String, age i32} and in typescript its type Person = {name: string age: number}

Similarly, Async code starts to look really ugly and overengineered in rust.

Sure

Multiple string types like &str, String, str, instead of just one “str” function

I know of &str and String, i’ve never heard of str though so you probably dont need it. &str is a string slice, aka a borrowed String. I generally say you shouldnt be using &str because generally if you get a lifetime error from using it, its because you’re doing it wrong, just use String while you’re learning the only real difference is that String is more verbose then ""

i32 i64 i8 f8 f16 f32 instead of a single unified “number” type like in typescript. Even in C you can just write “int” and be done with it so it’s not really a “low level” issue.

“int” from C is i32, these are int’s and float’s of various bit sizes. i32 = int 32bit, i62 = int 64 bit, f32 = float 32, u32 = unsigned (only positive) int32. but you dont usually need to specify this, rust has type inference. Also speaking of C, what about double, long, short, long long, unsigned long long, unsigned short…

Having to use #[tokio:main] to make the main function async (which should just be inbuilt functionality, btw tokio adds insane bloat to your program) yet you literally can’t write code without it. Also what’s the point of making the main function async other than 3rd party libraries requiring it?

I kind of agree? When async was initially designed it was done as a stackless minimal thing where we could build our own runners (like tokio) but no one really builds their own runners, they just use tokio.

Speaking of bloat, a basic get request in a low level language shouldn’t be 32mb, it’s around 16kb with C and libcurl, despite the C program being more lines of code. Why is it so bloated? This makes using rust for serious embedded systems unfeasible and C a much better option.

I don’t believe you, show me this project. As a personal project I have made a monolithic web server, that handles api calls, webpage calls etc, it uses axum, tokio and serde and when I run cargo build --release it compiles down to a 1.9mb binary. The only way I can see this happening is if you’re not using a release build, which is a concept you should understand as a JS dev.

With cargo you literally have to compile everything instead of them shipping proper binaries. Why??? This is just a way to fry your cpu and makes larger libraries impossible to write. It should be on the part of the maintainer to build the package beforehand and add the binary. Note that i don’t mean dependencies, I mean scripts with cargo install. There is no reason a script shouldn’t be compiled beforehand.

This argument has happened a few times that I know of. This is done for security purposes. If someone ships a binary blob you have to trust it to run, as a community, it was decided that we shouldnt do this.

Another major issue I’ve encountered is libraries in Rust, or lack thereof. Every single library in rust is half-baked.

I kinda also agree with this one, a lot of rust libraries are still in 0.x, I wouldnt call them all “half baked” though. If you search youtube you can find plenty of people using these libraries in prod.

“expect breaking changes” in the readme.

This is not specifically a rust problem this happens with every popular language & framework.

As for “memory safety”, it’s a buzzword. Just use a garbage collector. They’re invulnerable to memory issues unless you write infinite while loop and suitable for 99% of applications.

A garbage collector “freezes” you’re program when it runs usually. There are plenty of cases of people benchmarking rust against go, js, c#, java, etc rust performs vastly better.

Then use C or C++ if you really need performance. Both of them are way better designed than Rust.

Microsoft and Google came out and said that “~70% of their security flaws are a result of memory issues” or something like that. C and C++ are fundamentally flawed, which is why both of those companies have adopted rust.

There are apps with billions of users that run fine on php

True, but the number is going down, which implies a growing number of people choose to stop using PHP, we’re even doing it at work.

Rust is the most overwhelming proof possible to me that programmers are inheritly hobbists who like tinkering rather than actually making real world apps that solve problems

These are fighting words lol. I already mentioned Google and Microsoft have adopted rust for Windows, Chrome and Android. Other companies solving real world problems with rust include, Cloudflare, Dropbox, NPM, Yelp, Discord, Mozilla, Coursera, Figma, Facebook/Meta and Amazon.

Typescript is easy, rust is not. Typescript is therefore better at making things quick, the resourse usage doesn’t matter to 99% of people and the apps look good and function good.

What are you building where the end user doesn’t care if the app performs well? Not caring about resource usage results in poor performance which results in dissatisfied users/customers which stop doing business with you. Have you heard about the unending war in JS land against bundle size?

So at this point I’m seeing very little reason to continue. I shouldn’t have to fight a programming language

No one is required to like every programming language, If you don’t like rust, stop using it.

OP: “typescript is easy and rust is ugly”

Typescript :

export type PayloadActionCreator<
  P = void,
  T extends string = string,
  PA extends PrepareAction<P> | void = void
> = IfPrepareActionMethodProvided<
  PA,
  _ActionCreatorWithPreparedPayload<PA, T>,
  // else
  IsAny<
    P,
    ActionCreatorWithPayload<any, T>,
    IsUnknownOrNonInferrable<
      P,
      ActionCreatorWithNonInferrablePayload<T>,
      // else
      IfVoid<
        P,
        ActionCreatorWithoutPayload<T>,
        // else
        IfMaybeUndefined<
          P,
          ActionCreatorWithOptionalPayload<P, T>,
          // else
          ActionCreatorWithPayload<P, T>

(Wow, 14 posts in 2 hours on Lemmy… The old wisdom that the best way to start a discussion is to loudly complain about something rings true :P)

Cargo is doing too many things at once. It’s a build system but also a package manager but also manages dependencies? Idk what to even call it.

It’s still a build system; most (good) build systems also manage downloading and resolving dependencies. Having them all as part of the same tool makes everything slot together nicely.

Syntax is very confusing for no reason.

It’s not no reason; dealing with ownership is a complicated problem. It’s just that most languages tend to hide it and let the programmer tangle themselves in knots.

You keep talking about it being obvious what the code does but… Using :: over . helps clarify, at the call site, that you are using a “static” function rather than having to make the programmer look up the definition of the lhs.

Js is way more readable.

Pop quiz: Is this a copy or a reference?

let a = b;

You can just look at it and immediately know what the code is doing even if you’ve never coded before.

You can’t really… The JSON map object syntax isn’t actually intuitive to non-programmers. I’d argue that the rust version is more intuitive, since they can probably make a good guess based on the word “insert”.

Multiple string types like &str, String, str, instead of just one “str” function

These are distinct types with distinct meanings. JS and TS sacrifice some performance to make them seem like the same type, which may or may not be justified in your project.

i32 i64 i8 f8 f16 f32 instead of a single unified “number” type like in typescript.

JavaScript has three number types, ints, floats and BigInts. The former two are both called “number”.

Even in C you can just write “int” and be done with it so it’s not really a “low level” issue.

No you can’t. int is different sizes on different platforms. (EDIT: I was thinking about long. If you need more than 32 bits (which you do to store a pointer), that’s where the problem lies)

yet you literally can’t write code without [tokio].

I’ve never actually used Tokio. :D

Why is it so bloated?

Are you compiling at the same optimisation level, stripping debug info and statically linking libcurl in both cases?

Another major issue I’ve encountered is libraries in Rust, or lack thereof.

This is a big problem, I agree. Though to be fair, I’ve also encountered it with both NPM and PIP. Perhaps worse so there, because the compiler isn’t backwards compatible.

They’re invulnerable to memory issues unless you write infinite while loop and suitable for 99% of applications.

No they aren’t~ It’s easy to write code that hitches every few seconds (which kills games). And you also overlook the fact that a garbage collector is, quite frankly, a miracle of optimising compilers. I remember back in university being warned to remove the “next” pointer of graph nodes because otherwise memory would leak.

Then use C or C++ if you really need performance. Both of them are way better designed than Rust.

I develop professionally in C and C++. No they aren’t. At all. C and C++ are so loaded with footguns it’s a surprise people can get anything done in them without triggering UB.

Also, any program you write should be extensively tested before release

True. But nobody does that. And even if they did… Why not use a language that makes testing easier and faster?

you’d catch those memory errors if you aren’t being lazy

Not in any sufficiently large codebase.

that’s enough for the entire programming space to rank it year after year the greatest language

If you find that everyone in the world except you seems to be involved in some elaborate conspiracy, please check your reasoning.

And the thing is, that’s fine, the issue I have is people lying and saying Rust is a drop in replacement for js

Ehh… I don’t think it is. I think people interested in stepping up their programming game should give it a go, but branding it as a “noob friendly” programming language is going to put people off programming.

Typescript is therefore better at making things quick

Thing is, these “quick” programs tend to spiral out into huge megaliths of software that span several servers and support millions of users. And then the only person who knows what everything does gets hit by a bus, and so you have to figure out what thousands of lines of Typescript, PHP and Python code does.

Python, JS and php are good for firing out quick solutions, but once you get to the point where maintenance starts becoming more important than new features, it falls off hard. There just isn’t enough structure in the language to make it easy to figure out what code is doing.

I’m about to just give up and move on

Honestly, I bounced off of Rust the first time I tried it as well. I got frustrated about code not working, and just… Stopped using it. I then tried it again a few years later and everything finally “clicked”. Perhaps it’s the same with you? Give it a break for a bit, but don’t write it off yet. Come back to it later to give it another go.

Rust isn’t an easy language to wrap your head around if you aren’t familiar with the problems it’s trying to solve, but it’s not trying to be. Think of it as the drill sergeant that makes you stand up straight and become a better programmer.

rust is a systems/low overhead programming language. really not much of a point comparing js/ts and rust, since js is much higher level. you should be comparing it with c, c++, zig, maybe nim, etc

you also imply it’s pointless to have a language geared towards performance because computers are better now, but 1) programs run on more than just personal computers and you wouldn’t run js in an embedded system and 2) just because your computer can put up with poor performance and resource waste doesn’t mean that it’s sensible to do so (hello electron)

also, rust does more than just cosmetic improvements. it adds a layer of statically guaranteed memory safety that no other commercially viable programming language that i know of has. even if its syntax looked like ancient eldritch runes, it would still be an attractive language. the fact that it manages to do more than other languages while still having a decent syntax is amazing

you can dislike rust if you want that’s fine but you don’t need to try to shit on it just bc it’s not your cup of tea

If your primary exposure to programming is only typescript or JavaScript maybe you shouldn’t be jumping straight into something like rust. JS is a high level language and rust is aimed at the lower levels where things can’t be as automatic. There are many languages out there like C#, Kotlin and Swift that will help you get used to the idea of strong types and immutability.

Oh but in rust you learn more about computers/low level concepts, you’re just not good at coding”

Who cares? Coding is a tool to get shit done and I think devs forget this way too often, like if one works easier than the other why does learning lower level stuff matter?

This is pure junior energy. Or trolling, I honestly can’t tell.

Anti Commercial-AI license

Even though most of the specifics you point to are wrong, it’s a good point overall:

Rust, being #1, should be better than all other languages. The fact that it’s just decent makes it seem overhyped, and all the downvotes on haters make it look like a cult.

Back when it was small, the cult-like following was OK. But now that the language is becoming more mainstream I think the Rust evangelizers need to tone it down a bit or they risk pushing people away.

On your point, TypeScript is a decent language too. There can be two good things.

Frankly, all of your points sound quite ignorant. Syntax is literally just a matter of getting used to it. Comparing HashMap ergonomics doesn’t make sense, you should rather compare to struct construction. There are many good reasons for different string types and number types. There are good reasons not to bake in async. Rust documentation is in the code for a very good reason and it’s actually really nice to read docs like that (obviously read it on docs.rs, not in the code itself).

I could go on but there are answers to all of your specific qualms if you just bothered to look for yourself.

… the issue I have is people lying and saying Rust is a drop in replacement for js

I am genuinely curious whether you’ve actually seen this claim before, or if you badly misunderstood or are simply exaggerating a claim about Rust being a good language for web servers, or if you simply made this up as a straw-man. I can’t imagine anyone who knows what they’re talking about using those words I that order.

https://en.wikipedia.org/wiki/Poe’s_law

I think one thing to mention is that Rust is highly specific in what it does. In most of the examples you mentioned, string types, tokio::main, you can essentially just say that rust is more explicit. When initializing an integer variable in C using int, it’s not specified what use the integer is or whether it’s signed or not. i32, uint16_t you can see how it’s specified. Using tokio::main before your main function just specifies that you’re using the tokio asynchronous executor for your async code. In the case of string types, they all have different implementations which just help with being specific.

The reason I like Rust is because I know what’s happening when I read it. Did I have to read the whole async book to understand how the tokio::main stuff works? Yes. But now I understand exactly how it works. The problem I have with using Javascript is that it doesn’t have that high amount of explicitness(is that a word?). At the end of the day, if you’re using it for a personal project or you’re arguing for language supremacy, it really just comes down to personal preference.
