If you’re learning React, you’ve probably heard the terms “state” and “props.” But what do they mean, and how are they different? Let’s break it down.
- Props: Short for “properties,” props are used to pass data from a parent component to a child component. They are read-only and cannot be modified by the child.
- State: State is used to manage data that changes over time within a component. It’s mutable and can be updated using the
setState
method.
Here’s a quick example:
function Counter() { const [count, setCount] = useState(0); return ( <div> <p>You clicked {count} times</p> <button onClick={() => setCount(count + 1)}>Click me</button> </div> ); }
Understanding state and props is crucial for building dynamic React applications. Stay tuned for more advanced topics!
