What is Event Handling in React JS

In React, event handling is the process of capturing and responding to user interactions (such as clicks, key presses, form submissions, etc.) within components. React provides a streamlined way to handle events that differs slightly between class components and functional components using hooks.

Event Handling in Class Components

In class components, event handlers are typically defined as methods on the class and are bound to the instance of the component. Here's a basic example of handling a button click:

import React, { Component } from 'react';

class ButtonClick extends Component {
  handleClick = () => {
    console.log('Button clicked!');
  };

  render() {
    return (
      <button onClick={this.handleClick}>
        Click me
      </button>
    );
  }
}

In this example:

• `handleClick` is a method defined on the class component that logs a message to the console.
• `onClick={this.handleClick}` attaches the `handleClick` method as an event handler to the button's `onClick` event.

Event Handling in Functional Components using Hooks

With functional components, you can use the `useState` hook to manage state and `useEffect` hook for lifecycle events,
