On: Using TypeScript with React

[sli]

I've run into issues with TypeScript that forced me to cast string literal types to themselves before it would compile. So literally this code:

    'x' as 'x'

Nothing else would work, we were simply forced to do that. Avoiding `any` in all cases is simply not possible, as Redux will require you to use it at least once as of the last time I used TypeScript, which wasn't that long ago. Type discoverability for libraries was such a massive hassle that I don't see how other TS devs have gotten around it. Not everyone can use Visual Studio.

I don't find TypeScript's type system to be anywhere close to sound. Instead, it feels like it lies to me a lot. At least it has HKTs now, so that's nice. But I ended up moving to ClojureScript (and a little PureScript) and I've never looked back.

FYI you can use 'x' as const nowadays.

TypeScript does not have higher-kinded types. I'd link sources but it's difficult to prove the negative here. It just doesn't have any.
