Putting up https://github.com/facebook/react/pull/35129 again Reverted in https://github.com/facebook/react/pull/35346 after breaking main before security patch This change impacts output formatting in a lot of snaps, so is very sensitive to additions in main to the fixtures resulting in broken tests after merging, so we should try merge quickly after rebasing or do a fast follow to the merge with a snap update.
React Compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
