JavaScript setInterval Limits?

Question

I have an application using JavaScript's setInterval() to run a digital clock. I was wondering if it has a timeout, or limit, to the amount of times it can execute this function.

Answer 1

setInterval() will run infinitely.

If you wish to terminate the 'loop' you can use clearInterval. For example:

var counter = 0;

var looper = setInterval(function(){ 
    counter++;
    console.log("Counter is: " + counter);

    if (counter >= 5)
    {
        clearInterval(looper);
    }

}, 1000);

Answer 2

As others have mentioned, there is not limit to the number of times your interval will run, however if you intend to run a timer indefinitely you should consider the info here:

Minimum setInterval()/setTimeout() delay on background tabs

If your user is likely to tab-out, 1 second seems to be safe minimum interval
