Implement drop #29

Closed robb closed 11 years ago

robb commented 11 years ago 
Underscore.drop(@[ @1, @2, @3 ], 1); // 2, 3

Edit: take totally is head anyways

Can't you do that using filter?

robb commented 11 years ago

Actually, it's not possible to do that only with filter. You need access to the element's index whereas filter only passes the element to its block.

robb commented 11 years ago

I totally failed here, take is already implemented by head. That being said, something like underscore.js' initial could by useful:

Underscore.initial(@[ @1, @2, @3 ], 1); // 1, 2

essentially a dropRight
