Question

I need the function to repeat after 8 seconds the first time and then again after 30 seconds. I have used setTimeout but not sure if this is the way to go about it.
Thank you.

Answer 1

You could use a conjunction of setTimeout and setInterval:

window.setTimeout(function() {
    // this will run 8 seconds later

    window.setInterval(function() {
        // do here whatever you want to do at 30 seconds intervals
    }, 30000);    
}, 8000);
