An automated build-time compiler for React that eliminates the need for manual memoization (useMemo, useCallback).
React Compiler: The End of Manual Memoization
The **React Compiler** (formerly known as 'React Forget') is a milestone in frontend engineering. It automatically identifies where components need memoization and injects the necessary optimization logic during the build process.
Core Benefits
- Cleaner Code: Entire types of hooks (useMemo, useCallback) are largely deprecated for new development.
- Certainty: Eliminates 'missed memoization' bugs that were common in complex data-heavy applications.
- Grainy Updates: The compiler can optimize at a much finer granularity than manual React.memo ever could.
Strategy for 2026
Developers should focus on writing 'idiomatic React'—clean, readable code—and let the compiler handle the performance plumbing. Our **React 19 Action Workbench** is fully compatible with compiler-optimized components.
