an another way to do setInterval

In window object, there is a function setInterval which allows your to run a task repeatedly at an interval.

setInterval(doSomething; 100);

However, if the method last longer than the preset interval, it is not so efficient. We can use the follow function to make it more predictable.

loopTask(doSomething, 100);

function loopTask(fn, interval) {
       setTimeout(arguments.callee, interval);
