πŸš€ Frontend Tip of the Day: Enhancing Performance with React.memo() πŸš€

Did you know you can boost your React app's performance with just a single line of code? Meet React. memo()! 🧠

What It Does:
React.memo() is a higher-order component that optimizes your functional components by memoizing them. Essentially, it prevents re-renders when the props haven’t changed. This can make a noticeable difference in apps with many components or complex UI.

How to Use It:
Wrap your functional component like this:

const MyComponent = React.memo((props) => {
  // Component code will go here
});
Enter fullscreen mode Exit fullscreen mode

πŸ’‘When to Use:

  • For components that receive the same props frequently.
  • When a component re-renders unnecessarily due to parent updates.

⚠️ When NOT to Use:
Avoid using React.memo() on components that need to update frequently or on components with complex props that change frequently. Overuse can lead to unexpected bugs!

Happy coding! πŸ‘¨β€πŸ’»
