After so many years with React, here’s the truth most tutorials skip. React itself is rarely the problem. Architecture decisions are. Over time, I’ve learned that scalable React apps come from a few non-negotiables: • State lives as close as possible to where it’s used • Components optimize for readability before reusability • Side effects are isolated — not sprinkled • Memoization is a last step, not a default • If a component needs comments, it probably needs refactoring The biggest shift? Stop asking “How do I optimize this?” Start asking “Why does this component exist?” React rewards engineers who think in: → data flow → predictable renders → long-term maintainability Frameworks evolve. Solid fundamentals don’t. 💬 What’s one React habit you had to unlearn over time? #ReactJS #FrontendEngineering #SoftwareArchitecture #JavaScript #SeniorDeveloper #CleanCode #ScalableSystems
This hits home 👏 Most “performance problems” I’ve seen in React weren’t solved with useMemo or useCallback — they were solved by fixing the architecture. A few lines here really stand out: Keeping state close to where it’s used prevents entire trees from re-rendering and makes intent clearer Optimizing for readability first almost always leads to better reuse later Isolating side effects is what makes behavior predictable, not just “working” The mindset shift you mentioned is key: “Why does this component exist?” That question alone eliminates a lot of accidental complexity. One habit I had to unlearn: 👉 defaulting to abstraction too early. Most components never need to be reused — and that’s okay. React doesn’t reward cleverness. It rewards clarity, data flow, and decisions that age well.
Wise words, Sensei. But I have a question. Aren't comments inherently good especially if they actually better explain the code better for the next code reviewer? Ekta Rai
