 As part of the stable release, we've been making React Compiler easier to add to your projects and added optimizations to how the compiler generates memoization. React Compiler now supports optional chains and array indices as dependencies. These improvements ultimately result in fewer re-renders and more responsive UIs, while letting you keep writing idiomatic declarative code.
