React Functional Hooks Components > Stateful Class Components

With a quick glance at the examples below, it's immediately clear that with hooks:

  • managing state is simplified
  • there is no more dealing with "this"
  • code is much shorter
  • life is much better

Stateful Class Component

import React, { Component } from "react"; class ClickCount extends Component { constructor(props) { super(props); this.state = { count: 1 }; this.clickHandler = this.clickHandler.bind(this); } clickHandler() { this.setState({ count: this.state.count + 1 }); }; render() { return ( <div> <p>You clicked {this.state.count} times</p> <button onClick={this.clickHandler}>Click me</button> </div> ); } }
Enter fullscreen mode Exit fullscreen mode

Functional Component with Hooks

import React, { useState } from "react"; function ClickCount() { const [count, setCount] = useState(0); function clickHandler() { setCount(count + 1); } return ( <div> <p>You clicked {count} times</p> <button onClick={clickHandler}>Click me</button> </div> ); }
Enter fullscreen mode Exit fullscreen mode

Hooks was introduced with the release of React 16.8. Follow this link to learn more about React Hooks.
