i think the @react.dev Compiler team could include more of this type of messaging. i'm being a bit inflammatory here (and Haskell may not the best analogy), but the principle of "pure things are safe to move around" is fundamentally simple and has been known for decades. teach it to new generation!

Was just looking at some stuff on npm trends and this one struck me.

Truly shows how crazily styled-components took off back then, that it - as a react only library - is only now being overtaken in the last year by the de facto new standard for the entire web ecosystem.

Two days until Sanderson’s Wind and Truth and I’m really excited to spend December reading it. Probably losing some sleep for it too 😄
If you like Sanderson as well, what else would you tell me to read?

That wonderful feeling when you start a new project and the codebase doesn't _yet_ have any of those terrible mistakes you're about to make.
