Setup

var array=["foo","bar","baz","lorem","ipsum","lol","cat"];
  
  var func=function(){2+2};
  
  Array.prototype.forEach2=function(a){

    for(var i=0;i<l;i++)a(this[i],i)
  }
  
  Array.prototype.forEach2=function(a){
    var l=this.length;
    for(var i=0;i<l;i++)a(this[i],i)
  }
  
  Array.prototype.forEach3=function(a, ctx){
    var l=this.length;
    for(var i=0;i<l;i++)a.call(ctx,this[i],i)
  }
