HOW REACT COMPILER PERFORMS ON REAL CODE

Summary from the TLDR Web Dev newsletter

The React Compiler, a tool aiming to eliminate the need for manual memoization in React apps, is tested to see if it automatically optimizes code in real-world scenarios. Through testing on both simple examples and a real-world application (approximately 15,000 lines of code) in scenarios of initial load and interaction performance, most of the improvements are in interaction speed. While React Compiler offers performance benefits in many situations, it doesn't eliminate the need for manual optimization in all cases.
