I recently rewrote a small UI from Preact to Svelte and while it was certainly a learning experience, I have to say working with Svelte is fantastic. My only complaint is that the Typescript support isn't quite perfect yet, but it's already very functional.
I use Svelte + TypeScript in my personal projects, what issues did you run into?

Last I checked it was impossible to parametrize component type. In React you can write ` users={...} />`.

The UI components all have an else render if for some reason they're missing something / it avoids a crash (along with other easy to see / figure out protections)

Let's break down the terminology:
- hooks
- useEffect
- useHistory
- useSelector
- dispatch
- action
- useDispatch
- ducks
- Actions
- Epics (Observables)
- Sagas (generators)
- Reducers
Most of those terminologies don't come from a general programming paradigm, but are the domain language of specific libraries. And I've seen more, with some places establishing patterns like Compound/Molecule/Atom and such. There's no consistent, underlying principle with them, though. If you're invested in Sagas then you're stuck with a bizarre threading model implemented with generator functions and it's pretty much all-or-nothing. If you're invested in Redux then there's no breaking out of that either, you're always going to be contending with shared global state.
Javascript n00b question... is there any difference between onMount(() => { return listenForAuthChanges() }) and onMount(() => listenForAuthChanges()) ?

They are the same. It's a matter of style. For that matter, you could also write: onMount(listenForAuthChanges) which is technically simpler -- you're not constructing a new anonymous function. But if you wanted to extend the code (to say, add a console.log), you'd need to do the top version, which already has the braces. It's up to your judgment of what's clearer and likely to be more maintainable.
function log(expr) {
console.log(expr);
return expr;
}
onMount(() => log(listenForAuthChanges()))Half-OT: Svelte seems to be the pinnacle of the "bundling era" of frontend frameworks. What do you think comes next? XYZ-to-WASM? Back the roots with (non-)bundlers like Skypack? Anyone heard of next-gen experiments in that directions?
