18 Advanced React Techniques Every Senior Dev Needs to Know
As React applications grow more complex, the patterns that were “just fine” when you were starting out might start to feel limiting. Maybe you’ve built a successful MVP, but now you’re noticing subtle performance issues. Or perhaps your state management has gotten tangled, and your data fetching logic has mushroomed into something unrecognisable.
This happens to everyone as they move from junior to more intermediate or senior React work. The good news is that there are some advanced techniques that can help you simplify complex problems. In this article, we’ll walk through 18 such techniques, ranging from clever use of useCallback and ref, to harnessing Suspense for data fetching, playing with virtualisation, improving error handling, optimising performance, and more.
These might sound intimidating at first, but I’ll keep things approachable. By the end, you’ll have a richer toolkit to draw on when your codebase (and your career!) starts hitting those more complex challenges.
