Extending Javascript's Array

If you had told me a year ago that I'd not only be using Javascript on a daily basis, but actually enjoying it, I would have laughed in your face before making a cynical comment.

However, it's quickly becoming my favorite language simply because of how malleable it is. For instance, I sat down today to implement some syntactic sugar for Arrays and in less than a few minutes had extended the base Array object.

(function(){
  Array.prototype.first = function() {
    return this[0];
  };
  Array.prototype.last = function() {
    return this[this.length - 1];
  };
  Array.prototype.skip = function(num) {
    return this.slice(num,this.length);
  };
  Array.prototype.take = function(num) {
    return this.slice(0,num);
  };
}).call(this);

Sure, it's 14 simple lines of code, but they're methods that make sense at a glance and call to mind my old days using Linq in the C# world. Now all I have to do is pull in this little library, and all my Arrays have .last(), .first(), .skip() and .take().
