Summary: Compiler pass tabs are bolded when their contents have changed from previous passes; but currently the HIR and JS tabs are unbolded. Conceptually they should be, if HIR is "changed" from the source code and JS is "changed" from the last IR phase. In addition, the "show diff" option doesn't make a ton of sense for tabs that either aren't part of the pipeline (EnvironmentConfig) or (maybe more controversially, but imo) passes where the IR representation has changed since the last pass (BuildReactiveFunctions). This diff drops the button from those tabs. ghstack-source-id: 1d67e2f371a8c75792f7f6450f52ecbf79720c00 Pull Request resolved: https://github.com/facebook/react/pull/30151
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.
