#Determining how to access data based on the object type

  1. Call .class on the object that we have to see what type it is
  2. If it is an array, we can use the array methods (ie .first, .sort [])
  3. If it is a hash, we can use the hash methods (ie .fetch, h[:foo])
  4. If it is something else, we can ask what methods it responds to by doing foo.methods - Object.methods
