== What is a Ruby Array ==

A Ruby array is an object that contains a number of items. Those items can be variables (such as String, Integer, Fixnum Hash etc) or even other objects (including other arrays to make a multidimensional array). Once you have grouped all the items into the array you can then perform tasks like sorting the array items into alphabetical or numerical order, accessing and changing the value assigned to each array item, and passing the group of items as an argument to a Ruby function.
