Understanding the click effect

We passed an argument 'click' and I assume it is a text and not the actual click . Which part of the code is responsible of listening to the click?

The first argument we pass to the addEventListener() method is a string representing the name of the event type to listen out for. One of these events is called 'click', which indeed means that the user has clicked on our element.

Yes, "click" is a text string that names the kind of event you want to listen to.

The second argument to addEventListener is an "anonymous function" that contains the code that will be performed when a click happens. The code that is responsible for actually detecting the click (and then calling the function) is internal to the JavaScript engine.
