# React Compiler RC – React

**[React](https://daily.dev/sources/react)** · 6 min read · 15 upvotes · 0 comments

## Summary

React Compiler Release Candidate (RC) has been launched, offering optimizations via automatic memoization and support for optional chains and array indices as dependencies. Improvements include merging eslint-plugin-react-compiler with eslint-plugin-react-hooks for simpler setup and experimental support from swc and oxc. The RC is safe for production usage and backward compatible with React 17 and higher. Users are encouraged to provide feedback during the RC period, with continuous testing recommended for smooth upgrades.
