Setting Initial State with React's useState Hook
When using React, it’s often necessary to set an initial state for your components. This can be achieved using the useState hook.
Here's how you can set the initial state:
import React, { useState } from 'react';
function App() {
const [state, setState] = useState('Initial State');
return (
<div>
<p>{state}</p>
</div>
);
}
export default App;
In the above example, useState hook is called with the initial state 'Initial State'. It returns a pair — the current state value (state in our case) and a function that lets you update it (setState).
The useState hook is a built-in function in React that lets you add and manipulate state in functional components. This was not possible in earlier versions of React without converting the functional component into a class component.
