Ruby sees everything, from simple values (strings, integers), to complex data structures (arrays), as [Question 2]

Ruby is a [QUESTION 1] based, object oriented language. Every [Question 2] is an instance of a [QUESTION 1].

Ruby objects are most often handled via [Question 3] that represent them.

Every object is capable of understanding a certain set of messages.

These messages correspond directly to a [Question 4] - a named executable routine, whose execution the object has the ability to trigger.

Q - How is D3 different from user interaction manipulating DOM elements?

A - the DOM is manipulated by data

Q - how do I add D3 to my app?

Q - Assuming a model and controller exist, where would I write a custom helper method that is available application wide?

	Ruby is a CLASS based, OBJECT oriented language. Every _______ is an instance of a _______.

	Ruby sees everything, from simple values (strings, integers), to complex data structures (arrays), as _________.

	Ruby OBJECTS are most often handled via ________ that represent them.

	Every OBJECT is capable of understanding a certain set of MESSAGES.

	These MESSAGES correspond directly to a _________ - a named, executable routine, whose execution the object has the ability to trigger.


	Object identity
	expect(actual).to be(expected) # passes if actual.equal?(expected)

	Object equivalence
	expect(actual).to eq(expected) # passes if actual == expected

	Comparisons
	expect(actual).to be > expected
	expect(actual).to be >= expected

	class Car
	attr_accessor :color

	def speed
	speeda = 100;
	end

	def print_speed
	puts @speeda
	end

	Consider this code being found in the controller:

	$scope.stuff = ["a", "b", "c", "d"];
	$scope.changeIt = function(idx) {
	$scope.stuff[idx] = "x";
	};

	And this unordered list on the page:
