prototypes

[M.O.S. Studios]

I made this function, now it appears when ever i do a "for ... in". How do I attach it to the array object with out attaching it to all the instances

 

Array.prototype.leap = function(){
var y = this;
y.shift();
return y;
}

When you make something part of the prototype, you are making it part of all instances.  The Prototype is roughly equivalent to a class definition in javascript.
