React makes it incredibly easy to build interfaces — but writing React code that works is not the same as writing React code that scales . As applications grow, small decisions around component structure, state, effects, rendering, data fetching, and JavaScript can turn into major performance problems. This guide covers the principles, patterns, functions, optimization techniques, hacks, and common mistakes that help you write clean, predictable, maintainable, and high-performance React applications . 🧠 1.
