Question

I need one setInterval to start after another setInterval ends. Is there a way to do this with promises?

Ideally, I would like the code to look something like this:

for (i=0; i<5; i++){
  setInterval(fun_1, 1000)
  //wait until this is done
}

Answer 1

The setInterval calls the provided function after given interval of time until you clear its object. So you do not need a loop for this. You can use a counter to terminate it after counter reaches desired value.

Live Demo.

var myInter;
i = 1;
function fun_1()
{
   // some code
   if(i++==5)
      clearInterval(myInter);
}    

myInter = setInterval(fun_1, 1000);
