See https://github.com/facebook/react/issues/31551 for context We've rolled out internally with `enableTreatFunctionDepsAsConditional: false` and encountered no issues, but this is technically an unsound optimization as both flow and typescript have sources of unsoundness: - typing array accesses / other unknown keys as `TValue | undefined` (typescript's noUncheckedIndexedAccess) - explicit and inferred `any` - unsound typecasts Note that removing this optimization results in less granular dependencies for ~3% of files on a large Meta project ([link](https://www.internalfb.com/phabricator/paste/view/P1681742214)).
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.
