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']
