Almost three years since I helped ship the first VegaOS device on React Native. Awesome to see the progress—and to finally get it into other developers’ hands.

With React Server components, we’ll need to learn how to combine client and server components, use “different” data flow model. I appreciate Dan’s simplified explanation of the concept.

I'll definitely be turning on erasableSyntaxOnly:true in TypeScript 5.8! Very nice!
It enforces that all type definitions are annotations only, so when you strip the annotations, you end up with exactly the JavaScript you would have written without annotations (no enum, no namespace, etc)!
