React Complier - deep dive into performance

What exactly is the React Compiler, and how does it improve performance in real-world apps? In this lightning talk, Mykyta Roilian, Engineering Manager at LeanDNA, takes you on a deep dive into how the React Compiler optimizes things like useMemo, useCallback, memoized children, fallback props, and more. He also shares insights from testing the compiler in real-world-like scenarios—measuring bundle size, load speed, and framework-specific differences with Webpack, Vite, and Next.js.

If you’re curious about the future of React performance, this is the talk to watch.
