setTimeout or setInterval?

Question

As far as I can tell, these two pieces of javascript behave the same way:

Option A:

function myTimeoutFunction()
{
    doStuff();
           


        

Answer 1

The very difference is in their purposes.

setInterval()
   -> executes a function, over and over again, at specified time intervals  

setTimeout()
   -> executes a function, once, after waiting a specified number of milliseconds

It's as simple as that
