Idle Throttle - Just like a regular throttle, except that it waits for idle or timeout

idleThrottle.js

var idleThrottle = function(cb, timeout){
    var idleId;
    return function(){
        if(idleId){
            cancelIdleCallback(idleId);
        }
        idleId = requestIdleCallback(cb, { timeout: timeout });
    };
};
