Refusing rust and wasm is a signal you don’t care about code quality or security
See? You can keep playing that game all the way down to the most onerous language
Actually, if you really care about quality and types on the front end rust+wasm is not a bad idea 🤔
Now that I've typed that and read it back, were people using TypeScript for anything other than front-end web dev?
It was used pretty frequently for back end APIs too
That is disturbing. From my perspective, anyway. There are already so many great (and more appropriate) stacks for web backends, why Frankenstein a Frankenstein into it?
Well, usually because you've got a team of frontend folks needing to do a backend.
There's one other advantage, which is that you can have a compile-time shared model between backend and frontend. You also have that advantage with WASM, but not with a traditional backend/frontend technology split...
Compile time is my biggest issue with TypeScript. I've used JavaScript for decades with compile time measured in, what, a millisecond or two. Having to wait for TypeScript drives me nuts.
🤷 people like nodejs and people like type hinting and IDE reflection. Typescript helps a lot with that
We use TypeScript for our node.js backends.
We had two that started out vanilla, but it became too painful to maintain.
I wrote some TypeScript modules to process a bunch of documentation in markdown to a ton of output formats via pandoc + latex.
No real reason for it, except that I was able to start with the export module of a node-based thing written in JavaScript and iterate from there until I had a working system in CI/CD.
That's actually pretty neat!
Writing code that can’t be scientifically proven to be correct on all hardware it might run on means you don’t care about code quality. /s
The Internet is full of people with a bloated ego trying to justify their opinion and gatekeeping others.
I see this more and more in software as well.
Not sure if it’s always been like this, or if I just notice it more.
Same way there’s thousands of people giving you a guide to write a task list in , but as soon as you want to use anything slightly more complex than what you can learn from working a few hours with something you quickly run out of material and is usually left to fend for yourself.

Languages are just tools, so let's take the shortcut to the xkcd about editors 😁
Can wasm manipulate the DOM yet?
It can with some glue code that you better be writing in TypeScript if you care about code quality.
(As far as I know, it can't manipulate the DOM directly. Maybe things changed in the past couple months since I checked, but I doubt it.)
WASM allows arbitrary code execution in an environment that doesn't include the DOM... however it can communicate with the page where the DOM is available, and it's trivial to setup an abstraction layer that gives you the full suite of DOM manipulation tools in your WASM space. Libraries for WASM development generally provide that for you.
For example here's SwiftWASM:
It's pretty much exactly the same as JavaScript, except you nee to use JSObject to access the document class (Swift can do globals, but they are generally avoided) and swift also presents a compiler warning if you execute a function (like appendChild) without doing anything with the result. Assigning it to a dummy "underscore" variable is the operator in Swift to tell the compiler you don't want the output.
