Setup

var arr = [];
    for (var i = 0; i < 10000; i++) {
      arr.push({
        Number: i
      });
    };
    var e = null;
    
    function Named(o, i) {
      e = o;
    };
    
    var forEach = function (array, callback, scope) {
      for (var i = 0; i < array.length; i++) {
        callback.call(scope, i, array[i]); // passes back stuff we need
      }
    };
    
    Array.prototype.forEachShim=function(e,t){var n,r;if(this==null)throw new TypeError(" this is null or not defined");var i=Object(this),s=i.length>>>0;if(typeof e!="function")throw new TypeError(e+" is not a function");arguments.length>1&&(n=t),r=0;while(r<s){var o;r in i&&(o=i[r],e.call(n,o,r,i)),r++}};
