To create an array of numbers between 1
and 5
, I can do something like
the following:
(1..5).to_a
> [1,2,3,4,5]
However, what if I want an array of "1"
to "5"
? That is, what if I want
an array of consecutive numbers as strings?
I can just reuse the above and map them to strings like so:
(1..5).to_a.map(&:to_s)
> ['1','2','3','4','5']
Though, that seems more verbose than necessary. Ruby actually allows you to do ranges of characters. Which means that I can modify my original approach to look something like this:
('1'..'5').to_a
> ['1','2','3','4','5']
