3 Rules For React Hooks Many Don't Know (React Best Practices)

Unlock the secret to writing bug-free React code by mastering the 3 essential rules of React Hooks! 🚀 In this quick 1.5-minute guide, I break down the most important rules every React developer must follow:

1️⃣ Always call Hooks at the top level of your React function components or custom Hooks — never inside loops, conditions, or nested functions.
2️⃣ Use Hooks only inside React function components or your own custom Hooks — not in regular JavaScript functions or class components.
3️⃣ Avoid calling Hooks conditionally to ensure React keeps track of state and effects correctly.

Breaking these rules leads to unpredictable bugs and errors like "Hooks can’t be called inside conditions." I’ll show you why these rules matter and how to follow them easily.

🔥 Pro Tip: Use the official eslint-plugin-react-hooks to catch mistakes automatically!
