// State is essentially a global class variable
// that is modified when the component updates

class Clock extends React.Component {
  constructor(props) {
    super(props);
    this.state = {date: new Date()};
  }

  render() {
    return (
      <div>
        <h1>Hello, world!</h1>
        <h2>It is {this.state.date.toLocaleTimeString()}.</h2>
      </div>
    );
  }
}

import React, { Component } from "react";

class Counter extends Component {
	// you can either initialize state inside constructor
  	constructor() {
		super();
		this.state = {
			count: 1,
			tags: ["tag1", "tag2", "tag3"],
		};
	}
  	// or initialize the state as class field declaration
  	state = {
		count: 1,
		tags: ["tag1", "tag2", "tag3"],
	};
}

state in react

Comment

 The state is a built-in React object that is used to contain data or information about the component.
 A component's state can change over time; whenever it changes, the component re-renders.
