Find the first character in an array string

Question

I am trying to find the first character of a string inside an array. I would like to do something like this:

string = ["A", "B", 1234, 54321]
string[3].chars.first # => "5"

Doing "string".chars.first # => "s" only works for a string input.

Answer 1

You could change all of the elements of the array to strings then do what you were originally doing.

string = ["A", "B", 1234, 54321]
string.map { |x| x.to_s }[3].chars.first
=> "5"
