Solution 1
A functional component in React is defined using a JavaScript function. Here are two ways to define a functional component in React:
- Using a function declaration:
function MyComponent() {
return <div>Hello World</div>;
}
- Using an arrow function:
const MyComponent = () => {
return <div>Hello World</div>;
}
In both cases, MyComponent is a functional component that returns a React element (in this case, a div containing the text "Hello World"). When this component is used in a React application, it will render this div to the DOM.
