alt Hacker NewsFor the record, author is not crazy.
Svelte team also switched to JS with JSDoc a few months back[0].
You can see the majority of their repo is JS and not TS[1]
The cited reason[2]:
> As a Svelte compiler developer, debugging without a build step greatly simplifies compiler development. Previously, debugging was complicated by the fact that we had to debug using the build step. In addition, using JSDoc does not affect compiler’s development safety because the type is almost equivalent to TS.
As long as author ships type def, it should behave just like a TypeScript library for all intents and purposes.

Svelte is a bad example. They have roughly identical type checking before and after that switch. The switch is mostly just an aesthetic preference for one syntax over another and an ideological stance about being able to run code directly in a browser without a build step.

1. They still use types via JS Doc
2. They only switched to that for their internal development
3. User-facing code has all the type support and TS support you'd expect

And here's literally what he said:
--- start quote ---
Firstly: we are not abandoning type safety or anything daft like that — we're just moving type declarations from .ts files to .js files with JSDoc annotations. As a user of Svelte, this won't affect your ability to use TypeScript with Svelte at all — functions exported from Svelte will still have all the same benefits of TypeScript that you're used to (typechecking, intellisense, inline documentation etc). Our commitment to TypeScript is stronger than ever

Compare that to Nue's author's take
Svelte uses JSDoc and has TS validate that. Nue uses nothing. This analogy makes no sense.
Svelte still exposes types though, right? Like as a svelte user, you wouldn’t know it was written in JS?
I don’t use svelte, that’s just my understanding from when the TS -> JS switch was announced
From the link [3] you posted,
> If you're rabidly anti-TypeScript and think that us doing this vindicates your position, I'm about to disappoint you.
Rich and the rest of the Svelte team are still using typscript, just through JSDoc + type definition files.
In contrast the Nue team seems to want to keep the view layer untyped.

> real static typing (like Rust or Go) shines in business logic where it counts
it seems they don't consider typescript to be "real" static typing.
