Is setTimeout synchronous or asynchronous?
setTimeout is asynchronous, so the last line will not wait for setTimeout.
Should I use setTimeout or setInterval?
The only difference is , setTimeout() triggers the expression only once while setInterval() keeps triggering expression regularly after the given interval of time.

First a function to be executed and second after how much time (in ms). setInterval() executes the passed function for the given time interval.

So I tried to write a function (actually, 3 of them: setTimeout, setInterval and clearInterval) to write one line of code when I need it instead of, say, five. It is working, at least for the cases I tested. I understand that maybe something in that code is not right, maybe I forgot about something.
How to use setTimeout and setInterval in JavaScript?
