Ruby: What is the easiest way to remove the first element from an array?

Question

Lets say I have an array

[0, 132, 432, 342, 234]

What is the easiest way to get rid of the first element? (0)

Answer 1

This is pretty neat:

head, *tail = [1, 2, 3, 4, 5]
#==> head = 1, tail = [2, 3, 4, 5]

As written in the comments, there's an advantage of not mutating the original list.
