You can use this class github.com/mustafah/background-timer based on @jlafay answer , where you can use as follow:

coffeescript

timer = new BackgroundTimer 10 * 1000, ->
    # This callback will be called after 10 seconds
    console.log 'finished'

timer.enableTicking 1000, (remaining) ->
    # This callback will get called every second (1000 millisecond) till the timer ends
    console.log remaining

timer.start()

javascript

timer = new BackgroundTimer(10 * 1000, function() {
    // This callback will be called after 10 seconds
    console.log("finished");
});

timer.enableTicking(1000, function(remaining) {
    // This callback will get called every second (1000 millisecond) till the timer ends
    console.log(remaining);
});

timer.start();

Hope it helps, Thank you ...
