In order to make the program recognize the clicking of a button, the engineer should add an event listener to the JavaScript code.
An event is considered to be a vital part of JavaScript because a web page responds according to the event that occurred. Some events are generated by APIs and some are user-generated events. For example, clicking or moving the mouse button and pressing a key on the keyboard are user generated events.
In order to handle the user-generated events in JavaScript, an event listener is used. An event listener is a function or procedure in a JavaScript program that waits for an event to occur; such as pressing a key on the keyboard or clicking the button.
