    Is there a better way of performing array functions on a collection

    McShaman Level 1

      Collections... While having their advantages are a little bit painful as well. Want to pollyfill a lot of modern Javascript functions such as Array.forEach and Array.reduce but as I understand collections are not Arrays so pollyfilling the prototype is not going to help me too much.


      I wrote a little function that converts a collection to an array:


       * Converts Adobe collection objects to JavaScript arrays
       * @version 1.0.0
      function collectionToArray(col) {
        'use strict';
        var array = [];
        Array.prototype.forEach.call(col, function(itm) {
        return array;


      It works... It returns an array that I can perform native Javascript functions on. I just wanted to check with the community if this went against what is considered best practices for Adobe scripting.
