 Hash#diff is not provided by default, and monkey patching is frowned upon by some, but to provide a one way shorthand, use the following code snippet.
 
 ```ruby
   class Hash
     def diff(right)
-      HashDiff.right_diff(self, right)
+      HashDiff.left_diff(self, right)
     end
   end
 
   left  = { foo: 'bar', num: 1 }
   right = { foo: 'baz', num: 1 }
