X = -1

arr = [10, 20, 30, 40]
p arr[1..-1]

--output:--
[20, 30, 40]

But instead of splitting a super long string and then re-joining it, you 
can just split off the first word like this:

str = "a really long string"

first_word, the_rest = str.split(" ", 2)

p first_word
p the_rest

--output:--
"a"
"really long string"
