How React Compiler Performs on Real Code

The most talked-about news in the React community this year is probably the React Compiler. Everyone is looking forward to being saved from the re-render plague and never having to write useCallback/useMemo again.

But are we truly there yet? Can the React Compiler actually achieve those things? Do we need to do anything other than turning it on and enjoying a re-render-free life? I ran it on a few real-world apps to find the answer. Want to see the results?

In this talk, we’ll take a look at what the React Compiler is, what problems it solves, and how it performs on simple code examples and real-world applications.
