Event Handling in JavaScript

You can handle events in JavaScript to respond to user actions or interactions with your web page. Event handling allows you to create dynamic and interactive web pages that respond to user actions. Event handling in JavaScript involves code that executes when a specific event occurs, such as a button click, mouse movement, or keyboard input.

Event handling in JavaScript needs a few steps: select the target element, define the event handler function, and attach the event listener to the element.

Example: Event Handling in JavaScript

document.body = document.createElement('body');
var element = document.createElement('button');
element.textContent = 'Click me!';
element.id = 'myButton';
document.body.appendChild(element);
// JavaScript example for event handling
var button = document.getElementById('myButton');
button.addEventListener('click', function() {
  alert('Button clicked!');
  });
