EventChain: The Basics

eventChain.js

  // Defines a function that can fire sequential events.
  EventChain = function() {
    // Make sure we get called with new.
    if (this === window) {
      return new EventChain();
    }

    var steps = [];

    // Called every frame.
    var update = function() {
      if (steps && steps.length) {
        steps[0]();
      }
    };
