Javascript

For this challenge you will be using some meta-programming magic to create a new Thing object. This object will allow you to define things in a descriptive sentence like format.

This challenge will build on itself in an increasingly complex manner as you progress through the test cases.

Examples of what can be done with "Thing":

jane = Thing.new('Jane') jane.name # => 'Jane' # can define boolean methods on an instance jane.is_a.person jane.is_a.woman jane.is_not_a.man jane.person? # => true jane.man? # => false # can define properties on a per instance level jane.is_the.parent_of.joe jane.parent_of # => 'joe' # can define number of child things # when more than 1, an array is created jane.has(2).legs jane.legs.size # => 2 jane.legs.first.is_a?(Thing) # => true # can define single items jane.has(1).head jane.head.is_a?(Thing) # => true # can define number of things in a chainable and natural format jane.has(2).arms.each { having(1).hand.having(5).fingers } jane.arms.first.hand.fingers.size # => 5 # can define properties on nested items jane.has(1).head.having(2).eyes.each { being_the.color.blue.with(1).pupil.being_the.color.black } # can define methods jane.can.speak('spoke') do |phrase| "#{name} says: #{phrase}" end jane.speak("hello") # => "Jane says: hello" # if past tense was provided then method calls are tracked jane.spoke # => ["Jane says: hello"] 

Note: Most of the test cases have already been provided for you so that you can see how the Thing object is supposed to work.
