Honestly those usecases described here shouldn’t have been done in js in the first place.
Look, I'm in no position to talk seeing as I once wrote a cron job in PHP, but the profusion of JavaScript in the late aughts and early teens for things that weren't "make my website prettier!" feels very much like a bunch of "webmasters" dealing with the fact that the job market had shifted out from under them while they weren't looking and rebranding as "developers" whose only tool was Hammer.js, and thinking all their problems could be recontextualized as Nail.js.
Well I see huge benefits in building the tools used by a community with the technology this community masters. IMO the Python's stdlib sucks because it's written in C which is a huge barrier to entry.
Not all of the stdlib is written in C. Some parts cannot be Python because it’s critical code that needs to be as fast as possible.
Python is already slow for many use cases, if the standard lib was all built in Python it would be just too slow for much more use cases.
Can we please go back to making programs for the target OS and skip the browser dependency?
Sure! Here! Electron.
[Screams internally]
Browsers have almost become the OS. At least in user land.
JavaScript has its place as a lightweight runtime interpreter.
Rust has its place as a secure and modern way to engineer and produce dependable software.
Eh, it's not that lightweight, Lua is much better for that.
with wasm and friendly new web frameworks, the only thing keeping js alive is inertia
Essentially, JS is the new Flash….
The JS tooling universe has always seemed like a Lovecraftian hellscape to me. I've managed to stay away from it so far, but if I were caught in it, of course I'd be trying to escape any way I could. It sounds like Rust's attraction here has been as a viable escape corridor rather than anything about Rust per se.
In particular, I get that everyone wants their code to be faster, and I get that certain bloaty apps (browsers) need to get their memory footprint under control, and a few niche areas (OS kernels, realtime control) can't stand GC pauses. Other than that though, what is the attraction of Rust for stuff like tooling? As opposed to a (maybe hypothetical) compiled, GC'd language with a good type system and not too much abstraction inversion (Haskell's weakness, more or less).
Has Golang fizzled? It has struck me as too primitive, but basically on the right track.
Rust seems neat from a language geek perspective, but from what I can tell, it requires considerable effort from the programmer handle a problem (manual storage reclamation) that most programs don't really have. I do want to try it sometime. So the Rust question is intended as more inquisitive/head scratching rather than argumentative.
I think once you get into rust you just have a hard time going back, and it doesn't feel "hard" anymore. I can practically rust as easily as I can python for scripting and for API servers.
Rust really only gets hard when doing library development IMO. That's when you need lifetimes and well chosen types. But that's also why Rust libraries are superb.
- Rust is the best language for writing WASM in, so you can write Rust and run it in the browser without transpiling to JS.
- Rust isn't just about speed or GC pauses. Its type system is amazing and allows you to encode things that you cannot in any other mainstream language.
- It's so incredibly well designed, it fewla like that clip from Ricky and Morty where Morty feels what standing on a truly even plane feels like then has a panic attack when he leaves. Rust rethought everything from scratch, and isn't just some new syntax or fancy compiler tricks. No null, no exceptions, no inheritance, new typing capabilities, etc.
Go made some pretty poor design choices, and now even Google is choosing Rust for a lot of stuff instead.
I usually pick Rust for CLI tools because:
- It's statically compiled and isn't dependent on system binaries and won't break if there if the system has the wrong version like C/C++, allowing you to distribute it as a single binary without any other installation steps
- Still produces fairly small binaries unlike languages like Java or C# (because of the VM)
- Is a modern language with a good build system (It's like night and day compared to CMake)
- And I just like how the language works (errors as values etc.)
- It's statically compiled and isn't dependent on system binaries and won't break if there if the system has the wrong version like C/C++, allowing you to distribute it as a single binary without any other installation steps
You can do that with C++ too.

I mean, the jars are actually pretty small; but also I really don't get the storage argument. I mean we live in a world where people happily download a 600 MB discord client.

Meson exists ... as do others.
- And I just like how the language works (errors as values etc.)
Fair enough; though why? What's wrong with exceptions?
I work in a code base where I can't use exceptions because certain customers can't use exceptions, and I regularly wish I could because errors as values is so tedious.
Go is fine, but it has its flaws. I prefer Rust because:
- memory safety is a compiler check, not a runtime check, so you catch issues earlier
- locks contain their values, so you can't accidentally do anything unsafe
- no nil (
()
is semantically different), so no surprises with contracts - everything is an expression, which lends itself really well to FP concepts
- actual dependency management at 1.0
- pretty much no runtime, so calling from another language is super easy
- targets WASM and microcontrollers
- no pointers (not exactly true)
It takes longer to learn, but I'm about as productive with both now.
Maybe give it a try; it's my favorite language to write programs in now, it has an extremely good standard library, and for everything else there's a mass of high quality crates, its build system is actually competent and makes compiling on Windows or Linux trivial, plus many, many more quality of life features.
Has Golang fizzled? It has struck me as too primitive, but basically on the right track.
My biggest issue with Golang by far is the close tie to Google. They are not our friendly innovator, time and time again they make decisions that will help them earn more ad money, and nothing else. And they have a lobg history of releasing something and then never fix the issues with it, and then more or less abandon it.
Other than that there are afaik some other issues with go, I'm not an expert but from what I hear the GC is quite aggressive and you can't tell it to run when you want. Doing something time sensitive? Well, bad luck. GC time!
Thank god.
Nom nom nom
Everything eventually becomes a crab.
That means eventually everything tastes great when smothered in butter. 🤤
Can browsers run rust in the front end instead of javascript, or is it limited to build time and backend stuff?
Sort of, browsers can run rust code through webassembly. But i dont think this is a full replacement for JavaScript as of yet.
Yeah, you need to have some JS to manipulate graphics, so the Rust web frameworks have a JS shim to do that and communicate with the WebAssembly Rust code as necessary. It works surprisingly well tho.
Is this a 2yo write up, considering the last update was in 2023?
Originally 4 years old at this point it looks like, and the great shift to wasm has failed to manifest.
It was recently shared on Hackernews, I assume that's why it's showing up here now.
Guten Appetit!
Can I just say how beautiful that page is? Such a delight to read the text on it. The legibility. The simplicity. 😙👌
