I often feel this way about heavy use of typescript generics. The more you lean into the crazy (and awesome) world of generics, the more inscrutable the code becomes to anybody who isn’t a generics wiz. It’s really like an extra language stacked on top of JS. I’ll come back to code I wrote a year ago, and it’ll take me a full day to figure out the types.

But the simplicity of using a library or set of functions that have really nice generics? So awesome. The intellisense and type errors alone can almost be a decent form of documentation.

The source becomes hard and weird to change, but the end result is a very nice DX
