Event Handling

Handling events in JavaScript allows you to respond to user interactions, such as clicking a button, submitting a form, or hovering over an element. Event handling is an essential part of creating interactive web applications.

To handle events in JavaScript, you can use event listeners. An event listener is a function that gets executed in response to a specific event.

Here's an example of adding an event listener to a button element:

1const button = document.getElementById('myButton');
2
3button.addEventListener('click', function() {
4  // Code to handle the click event
5});

In this example, the event listener is added to the button element with the id myButton. When the button is clicked, the function inside the event listener is executed, allowing you to perform the desired actions.

You can attach event listeners to various HTML elements and listen for different types of events, such as click, submit, keypress, mouseover, and more. Event handling in JavaScript provides a way to make your web applications interactive and responsive.
