Where are events covered?

Hello. I recently started and almost finished JavaScript basic course. My goal is to go into three.js programming after this. I was told that for three.js beginner level you would need JavaScript basics like functions, loops arrays… and also events. I went trough all the things listed so far, but I can’t seem to find where and in what course JavaScript ‘events’ are covered?

There’s some stuff on events in Building Interactive JavaScript Websites and a few bits in Learn Node.js and maybe in some projects in Learn Intermediate JavaScript I think.

Although it may help to research events separately for more info too. I use Mozilla as a reference sometimes.

Thanks, I took a look and I agree that events would be better to research on own probably.
