State in React

Basic State

State in React components is essential to manage and communicate data in your application. It is represented as a JavaScript object and has component level scope, it can be thought of as the private data of your component.

In the example below we are defining some initial state in the constructor function of our component and make use of it in the render function.

class ExampleComponent extends React.Component {
 // Set-up our initial state
 this.state = {
 greeting: 'Hiya Buddy!'
 render() {
 // We can access the greeting property through this.state
