Analysis of Apple’s rubber band scrolling

January 6, 2013

(function() {
    var defaultFrameRate = 20, // fps lock for old browsers
        // This is the default fallback throttle function
        framerateThrottle = function(callback) {
            return _.throttle(callback, 1 / (defaultFrameRate * 1000));
        };

    // Feature detection - should have requestAnimationFrame
    if (window.requestAnimationFrame) {
        framerateThrottle = function(callback) {
