Background

We have learned about DOM and its manipulation through JavaScript. We have yet to dynamically change DOM on a web page with listeners using JavaScript asynchronously. Let’s jump into the events on a web page! We can use asynchronous JavaScript to make dynamic changes and react to the events.

Introduction to events

Events are actions that occur on the browser or on a web page. JavaScript can listen to these actions to do certain tasks. Some events are:

• load: Event of loading the element on a web page
• click: Event when an element is clicked on a web page
• keypress: Event when a user presses a key

In JavaScript, we can leverage these events through the Event object by adding listeners. This makes a more dynamic and interactive web page.
