Suspending a js script until an event occurs

Is there any way to suspend a js script until some event like a mouse click on a button occurs?? I mean the script should pause its execution and resume again when the event occurs. I am kind of new to Javascript and even after a thorough search on the net couldn't find a solution!!

If what you are trying to pause is a function which would otherwise keep looping, I've come up with a good solution: https://stackoverflow.com/a/47841425/2884291

JS is single threaded and multithreading can be done us Web Workers only. As far as I know.

However if you have only a little script which you want to suspend, you can have a global variable/flag and simply in your script(I somehow believe it's a loop or event driven function) have a check for that flag. In this case:

var flag = false;

...
if (flag) {
   do your code
} else {
   do nothing or return if in function
}

Once you want to continue, just set flag = true;

JavaScript is single threaded with no preemption when events occur. It's not possible.
