Tracks locations for reactive scope dependencies, both on the deps and portions of the path. The immediate need for this is a non-public experiment where we're exploring type-directed compilation, and sometimes look up the types of expressions by location. We need to preserve locations accurately for that to work, including the locations of the deps. ## Test Plan Locations for dependencies are not easy to test: i manually spot-checked the new fixture to ensure that the deps look right. This is fine as best-effort since it doesn't impact any of our core compilation logic, i may fix forward if there are issues and will think about how to test.
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.
