Rules of React Hooks ✅

Here are the core rules and best practices for using React Hooks effectively:

1. Only Call Hooks at the Top Level
   ⚠️ Do not call hooks inside loops, conditions, or nested functions.
   📌 Example: Always use hooks in the outermost scope of your component.

   

2. Use the useEffect Hook for Side Effects
   📌 Clean up resources like subscriptions or timers in the return statement.

   

3. Avoid Using Hooks in Non-Component Functions
   ⚠️ Hooks must be called from React components or custom hooks.
   📌 Learn more about React Hooks fundamentals for deeper insights.

4. Use useState for State Management
   📌 Always initialize state with a default value in the component scope.

   

5. Follow the Rule of No Mutable Variables in the Component
   ⚠️ Avoid using let or var in the component body. Use const instead.
