Setup

var array=["foo","bar","baz","lorem","ipsum","lol","cat"];
  
  var func=function(){2+2};
  
  Array.prototype.forEach2=function(a){
    var l=this.length;
    for(var i=0;i<l;i++)a(this[i],i)
  }
  var forEach2=function(a,c){
    var l=a.length;
    for(var i=0;i<l;i++)c(a[i],i)
  }
  
  Array.prototype.map2=function(a){
  var l=this.length;
  var array=new Array(l),i=0;
  for(;i<l;i++){array[i]=a(this[i],i)}
  return array;
