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
});
💡 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! 👨💻
