> "type hell" seems to be far worse than "dependency hell," where the open source type definitions you use can have minor inconsistencies with each other, many of which are out of your control, causing lots of useless type errors in any project with even medium complexity.

Tried twice to wrap my head around what you are even talking about.

TypeScript is totally wonderful. It's also optionally typed.

I use it on a non trivial project with multiple teams.

Was introduced to it last year and it's fantastic compared to plain js.

This was generated by one line of code, simply applying the hoist-non-react-statics library as recommended by the official React docs https://reactjs.org/docs/higher-order-components.html#static...

JavaScript in many cases can be too dynamic to be properly typed. I'd rather have it than not - it has saved my ass a good number of times - but let's not pretend TS/Flow is totally wonderful.

Error messages like that are pretty bad, yeah. I'm still a fan of TS myself though, the challenge is that there's some less-well-designed JS libraries that are, like you said, too dynamic to be properly typed.

It's bringing OOP back from having almost been forgotten, and with it, a reminder of proper library design and data types.

I've only recently started into React, but my impression is because many React teams use Flow or nothing at all, the Typescript types definitely lag behind releases.

At some point I hope to sit down and start filing bugs/sending PRs to fix many of the React Typescript types I find, but in the meantime there are several React modules I've replaced the with just `declare module 'react-thing'` to jus any-type it and move on.

Looks like a jetbrains IDE, I'm a massive fan of intellij and it's my goto programming environment but it's type error messages with typescript are terrible compared to vscode (enough that if I can't understand what the hell it's saying I'll boot vscode).

It's about the one thing I can really ding intellij for at the moment.
