Setler [38]

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. Therefore based on the scenario given in the question statement, the engineer should use an event listener to his JavaScript code so that the code can recognize the click of the button.
