Event handling is an important part of creating dynamic and interactive web pages with JavaScript. Events are actions or occurrences that happen in the browser, such as a user clicking a button, scrolling the page, or submitting a form. Event handling involves writing JavaScript code that responds to these events by executing a function or set of functions.

To handle events in JavaScript, you can use the addEventListener() method, which allows you to specify a callback function that will be executed when the event occurs.

There are many different types of events that you can handle with JavaScript, such as mouse events, keyboard events, form events, and more. The addEventListener() method can be used to attach event listeners to any DOM element that supports events.
