There's no such thing as 'multi-threaded React'. JavaScript runs in a single thread unless you use web workers, which React doesn't (this was a popular idea a few years ago, but people have since come to accept that it a

Why do any of those things need to be native apps, rather than instantly-accessible, no-install-required URLs that come with all the protections of the web's security model?

Sure, it's easy: don't serve sourcemaps. This isn't specific to Svelte though. In fact your code is much more obfuscated with Svelte than with most comparable tools, since you're not serving the code you actually wrote

That code appears nowhere in the documentation. Regardless, you appear to be confused about the meaning of the word 'mutable'.

Honestly, the biggest blocker to us having a 'blessed' story around testing isn't figuring out how to test (which is relatively straightforward), it's figuring out what to test. Do you really need to test that `<p

It can't 'compile' to HTML, because it doesn't know at compile time what data you're going to give the component. Instead, if you compile with `ssr: true`, the JavaScript it generates is a module that generates HTML

Our vision for how to build large apps with Svelte is best represented by Sapper — https://sapper.svelte.technology — which is a Next.js-style framework. Right now it's a bit out of date, we need to spend some time bringing

It's only the documentation that's a TODO, you can use them currently. Just pass `customElements: true` to the compiler and specify a tag, either as `tag: 'my-tag'` or in the component itself with `<svelte:options tag

It was all built in-house by me and other members of the Svelte community. The playground widget is technically a standalone thing, but it wasn't totally designed to be used outside https://svelte.dev so may be a bit warty!
