##Cheesy Mac Attack Hash We're going to build a hash that stores a recipe for homemade mac and cheese.

This is a test driven lab so first fork and clone the lab or click Open in Nitrous. Then open recipe_hash.rb and follow the instructions in the file! Don't forget to run learn (from the main directory for this lab) as you work to make sure you are passing the tests.

More information about hashes can be found in the Ruby docs.

And as a reminder, a hash is a data structure, similar to an array, but instead of using numbered indexes to access data we linke each piece of data with a string (or symbol). Hashes looks like this:

student_ages = {
  :victoria => 25,
  :arel => 27,
  :carley => 25, 
  :al => 26
}

In this example, the hash is stored in the variable student_ages. Each age is stored in a key value pair: the name is the key and the value associated with it is the age. If you wanted to access the age of Arel, you would access it by calling student_ages[:arel]. Hashes are great because they allow us to store data with additional context. If we just stored everyone's ages in an array student_ages = [25, 27, 25, 26], we would have know idea which age belongs to whom!
