Optimizing React Performance at Scale

React is fast, but it's easy to make it slow. As applications grow, re-renders become the enemy of performance.

We explore advanced techniques like useMemo and useCallback not just as band-aids, but as architectural principles. Virtualization for long lists and code-splitting via dynamic imports are mandatory for maintaining 60fps on mobile devices.

The Server Components Era

With the rise of React Server Components (RSC), we can now move heavy computations to the server, sending zero bundle size for those components to the client. This is a paradigm shift in how we build interactive UIs.
