Answer 1

This answer is for everyone that realizes the accepted answer does not address the question as it currently written.

The question asks how to find a value in an array. The accepted answer shows how to check whether a value exists in an array.

There is already an example using index, so I am providing an example using the select method.

1.9.3-p327 :012 > x = [1,2,3,4,5]
  => [1, 2, 3, 4, 5] 
1.9.3-p327 :013 > x.select {|y| y == 1}
  => [1]
