Not sure how much you care, but your example for .slice() is wrong. .slice(1,3) will give you elements two and three. You're looking for .slice(0,3)

  It gives elements one and two. That's one to three, non-inclusive. If we wanted elements one thru three, that's a different matter.

    [1,2,3].slice(1, 3) > [2, 3]
