Microsoft is making TypeScript 10x faster with native implementation in Go (www.techspot.com)

Bigger TypeScript projects should now become much more manageable in all code editors

Eh, not entirely. Typescript will build faster and the text editor can parse it quicker but once it hits the browser no speed is gained. It's kinda stated in the article but it dances around it quite well I wouldn't blame you for missing it.

This just makes transpilation quicker along with some other benefits while working with it in editor. It's still just JavaScript in the end this just gets it there quicker. Still very cool though.

I feel this should be obvious to anyone who knows anything about programming, because typescript is just a development tool not a runtime.

I... Don't know about that. I mean, you could implement a browser or even a runtime library that used typescript (or a subset thereof) to directly write LLVM; it would take a lot of work, but typescript doesn't have to just be for transpiling.

But there is no such implementation AFAIK? How is it making Typescript faster if it's a completely new implementation?

But certainly, in theory it could become unshackled from JavaScript. Have there been any serious attempts to do so though?

Well a new implementation running TypeScript could be 10x faster than the traditional e.g., NodeJS implementation or something; it's not unusual for things to be compared in such a way.

No idea! :)

There is a serious attempt for that actually: https://www.assemblyscript.org/

It doesn’t offer full compatibility with the regular TypeScript though, despite being very similar.
