🌟 DOM Manipulation in React JS: What You Need to Know 🌟
🔑 React’s Virtual DOM
React uses the Virtual DOM to calculate the minimal changes needed, improving performance compared to direct DOM manipulation.
❓ When Should You Manipulate the DOM?
- Working with third-party libraries (e.g., jQuery).
- Handling animations or focus.
- Integrating non-React components.
🛠️ How to Manipulate the DOM in React
React provides Refs for DOM manipulation. Here’s a basic example using useRef to focus an input:
const DomManipulationExample = () => {
const inputRef = useRef(null);
const focusInput = () => inputRef.current.focus();
return (
<div>
<input type="text" ref={inputRef} />
<button onClick={focusInput}>Focus Input</button>
</div>
);
};
🔎 Best Practices
1. Use Sparingly: React handles updates efficiently. Rely on state and props for most UI updates.
2. Use Refs Carefully: Direct DOM manipulation can lead to issues if overused.
