Those got my attention.
Clicking the answer of led me to a reassuring answer, as I expected without a doubt. But I also had my own thoughts on the topic, so I though "let me write them"!
When I started learning about JS in the late 90's, the vast majority of the developers used it to make snow rain on the website at Christmas, show alert and dialog boxes, and do all weird kinds of effects. It was kinda fun, but only the pros would use it to create things more complicated than a poll or something.
If anyone tells you any different, maybe it's because their favorite programming language is much less popular and they hope one day people stop using JS and use the one they invested so much into :)
