Introduction

As a developer, you must have come across the term “Javascript Event Target”. This is an essential concept in Javascript that is often utilized in web development. Understanding the event target is crucial in creating interactive web pages that respond to user actions. In this article, we will explore Javascript Event Target in detail, including its definition, how it works, and its relevance in web development.

What is Javascript Event Target?

Javascript Event Target refers to an object in Javascript that receives an event when it occurs. An event is an action or occurrence that happens in a web page, such as clicking a button, hovering over an image, or submitting a form. The event target is the element that triggers the event, and it’s usually the element that the user interacts with.
