React Js- Use State Hook In Functional Component

In React, the useState hook is a feature that allows us to add state to functional components.

Before the useState hook, we had to use class components to add state to our React applications. However, with the introduction of hooks in React 16.8, we now have the ability to use state in functional components as well.

Let’s take a look at how we can use the useState hook in a functional component:

    {`
    import React, { useState } from 'react';

    const ExampleComponent = () => {
      // Declare a new state variable, which we'll call "count"
      const [count, setCount] = useState(0);

      return (
        

          
You clicked {count} times
           setCount(count + 1)}>
            Click me
          
        
      );
    }

    export default ExampleComponent;
    `}
  

In the above example, we import the useState hook from the ‘react’ package and then declare a state variable called “count” using the useState hook. The useState hook takes the initial state of the variable as an argument.

We then use the count variable and the setCount function in our component to keep track of the number of times a button is clicked. When the button is clicked, we call setCount to update the state of the count variable.

Using the useState hook in functional components allows us to manage state and make our components more flexible and reusable. It also simplifies the process of adding state to our React applications.

Overall, the useState hook is a powerful feature in React that enables us to manage state in functional components. It’s a great tool for adding dynamic behavior to our applications and making our components more interactive.
