Question

(ruby 1.86)

I have an array made up of arrays like:

>> myArray 
=> [["apple", 1], ["bananna", 2], ["peach", 3], ["orange", 4]]

I know I can use the detect method to find the first instance of ‘orange’ in index[0] of the sub-arrays in MyArray:

myTest = (myArray.detect { |i| i[0] == 'orange' } || []).first
=> orange

If it’s possible, how can I have the detect method return the value of the sup-array index position 1. Like, i[0] is being returned, but when i[0] == ‘orange’ I need i[1] returned.

I need to search for ‘orange’ and have the return value be 2.

Thank You!

I suppose you want the return value to be 4. No need for #detect:

ar = [["apple", 1], ["bananna", 2], ["peach", 3], ["orange", 4]]
puts ar.assoc("orange").last

#=> 4
