# Create an Array of Stringed Numbers
|
|
|
|
To create an array of numbers between `1` and `5`, I can do something like
|
|
the following:
|
|
|
|
```ruby
|
|
(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:
|
|
|
|
```ruby
|
|
(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:
|
|
|
|
```ruby
|
|
('1'..'5').to_a
|
|
> ['1','2','3','4','5']
|
|
```
