Advanced React & Testing
For developers who already know React: go deep on performance, advanced patterns (compound components, custom hooks), and state architecture at scale, then master testing with Jest, RTL, and Cypress, capped with a fully tested component library.
Learn why React apps slow down and the tools to fix it: memoization, avoiding unnecessary re-renders, and profiling real components.
- Why unnecessary re-renders happen
- useMemo and useCallback in practice
- React.memo and when it actually helps
- Measuring performance instead of guessing
- Common performance anti-patterns
- Modern React performance patterns
- Code splitting and lazy loading
- Virtualizing long lists
- Avoiding prop-drilling-driven re-renders
- When optimization is (and isn't) worth it
