Does "setinterval" make the event occur periodically?

Answer 1

I think it does. in other languages a while loop is used for this behavior. but it looks like in JavaScript the behavior continues until it's cleared.

Answer 2

yes it does. whatever value you pass as the second argument will be your period (in milliseconds)

Answer 3

Take a look at this example I did so you can have a better understanding of setInterval:
