Im wondering if there 's Head- and Tail-methods in Ruby or Ruby on Rails (framework)

Question

I'm just wondering if there's something similar in Ruby or RnR?

This post: Why no tail() or head() method in List to get last or first element? talks about this about Java but I'm wondering the same thing but in Ruby or RnR.

Thanks for yr time!

Answer 1

Here is one possiblity:

head, *tail = args

It uses the Ruby splat operator.

Example:

args = [1, 2, 3, 4, 5, 6, 7, 8]
# => [1, 2, 3, 4, 5, 6, 7, 8]
head, *tail = args
head
# => 1
tail
# => [2, 3, 4, 5, 6, 7, 8]
