We played the newlyweds game with @cedric_dev, @tido64, & @DelphineBugner. What we learned? ➡️ Everyone hates class components. ➡️ Build fix horror stories: "wrote my own CLI" & "unplugging the external screen". ➡️ Don't put everything in one `index.ts` file! Full game ⬇️

"The biggest performance issue in React is just rendering too much". @jmeistrich argues the real bottleneck in RN isn't lists, it's state. React's top-down render isn't performant by default. His fix: a signal-based system where components subscribe only to the state they need ⬇️

React Native is 10 years old, but stability is the new hot topic. @chris_trag & @moyessa (@Amazon) argue stable core just means more expansion (TVs, AR, Web). This puts a huge burden on library devs. They explain why brownfield is the real path to adoption ⬇️
