My issue with typescript... and, correct me if I'm wrong... is it doesn't exist without Javascript. Typescript needs to be compiled down into Javascript to be run. It has no stand alone interpreter (that I'm aware of) and definitely not one baked into web browsers or NodeJS (or adjacent) tools. In essence, Typescript is jank sitting on top of and trying to fix Javascript's uber jank, simultaneously fracturing the webdev space while not offering itself as a true competitive and independent language for said space.
That's my amateur two cents for what it's worth.
Just fyi, while they don't help with running TS in the browser, the Bun and Deno runtimes both natively run TS without any compilation.
That's not true, deno compiles TypeScript to JavaScript, it just does it transparently. The code still runs on v8.
V8 also doesn't run js, it does some byte code compilation stuff amongst other things, then interprets that. But that's all a bit pedantic too, V8 runs js, deno runs ts.
fwiw https://deno.com even has as one of their first bullet points that they have "native support for TypeScript and JSX"
Sure, but part of the claim was "without any compilation". But bun/deno do compile TS into JS.
