Re-explain
React Element: A plain JavaScript object that describes what should appear on screen. It's the smallest building block of React apps.
const element = <h1>Hello, World!</h1>;
React Component: A function or class that returns React elements. Components are reusable and can accept inputs (props).
// Function component
function Welcome(props) {
return <h1>Hello, {props.name}</h1>;
}
// Class component
class Welcome extends React.Component {
render() {
return <h1>Hello, {this.props.name}</h1>;
}
}
