> Svelte team also switched to JS with JSDoc a few months back

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

> Rich Harris (Svelte team) even had a comment on this on HN[3].

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
