Using UseState in React Js Toggle Buttons

React Js is a popular JavaScript library for building user interfaces, and one of its key features is the use of hooks. useState is one of the most commonly used React hooks and is a great way to manage state in functional components.

Toggle buttons are a common UI element in web development, and they are used to switch between two states. In this article, we will explore how to create toggle buttons in React Js using the useState hook.

Creating the Toggle Button Component

To create a toggle button component in React Js, we first need to import the useState hook from the React library. Then, we can define our functional component and use the useState hook to manage the state of the toggle button.

Here’s a simple example of a toggle button component using useState:

“`jsx
import React, { useState } from ‘react’;

const ToggleButton = () => {
const [isToggled, setIsToggled] = useState(false);

const handleToggle = () => {
setIsToggled(!isToggled);
}

return (

{isToggled ? ‘On’ : ‘Off’}

);
}

export default ToggleButton;
“`

In this example, we define a state variable isToggled and a function setIsToggled to update the state. We use useState to initialize the state to false, indicating that the toggle button is initially in the “off” state. When the button is clicked, the handleToggle function is called to update the state based on the current value.

Using the Toggle Button Component

Once we have created the toggle button component, we can use it in our main application component. We simply import the ToggleButton component and include it in our JSX code.

Here’s an example of using the ToggleButton component in a main application component:

“`jsx
import React from ‘react’;
import ToggleButton from ‘./ToggleButton’;

const App = () => {
return (

);
}

export default App;
“`

When the main application component is rendered, it will display the ToggleButton component, allowing the user to toggle the button between the “on” and “off” states.

Conclusion

Using the useState hook in React Js is a powerful way to manage state in functional components. By creating a simple toggle button component and using the useState hook, we can easily add interactive UI elements to our web applications. Whether you are building a small personal project or a large-scale application, understanding and using the useState hook can greatly enhance your React development skills.

So go ahead and start experimenting with toggle buttons and useState in your React Js projects! Happy coding!
