Is there a way to find the position of a specific string or number stored in an array?
Is there a way to find the position of a specific string or number stored in an array? (without the aid of some type of for loop to test each element of the array)
I'm just curious because there is a way to do this Mathematica and it can be helpful. Thanks in advance for any light someone might be able to shed on this.

There is a way to check this in ruby with
index, rather than writing your own for loop. Though I haven't checked the ruby source code, I have a hunch under the hood this is just going to run a for loop for you.
animals = ['dog', 'cat', 'eagle'] animal = 'eagle' animals.index(animal) => 2 # you might also be interested in include animals.include? animal => true
Forgive me if this is too basic or if I have misspoke. I am not a rubyist.
