What is the way to iterate through an array in Ruby?
This will iterate through all the elements:
array = [1, 2, 3, 4, 5, 6] array.each { |x| puts x } Prints: 1 2 3 4 5 6
This will iterate through all the elements giving you the value and the index:
array = ["A", "B", "C"] array.each_with_index {|val, index| puts "#{val} => #{index}" } Prints: A => 0 B => 1 C => 2
