	# Arrays are useful for storing different types of data
	diverse_array = [1,2,"abc",[9,9,"zzz"]]

	# Hashes are useful for lookup data
	lookup_hash = {
	ssn => 1234,
	dob => "December 25th, 2000",

	# Initialize Array
	my_array = []

	# Example Array
	my_array = [1,2,3,4,5]

	# Array indexes display items starting from 0 to -1
	my_array[0] = 1
	my_array[-1] = 5

	// Accessing JavaScript Object Properties

	// Dot Notation
	console.log(skateboarder.name) // Prints "Rodney Mullen" to console.

	//Brackets
	console.log(skateboarder[wheels]) // Prints "undefined" to console.

	// The line above evaluates wheels to return "Spitfire", then return undefined as there is no property named "Spitfire".

	# Accessing Ruby Hash Value
	print grades[:Jane] #=> prints value 89
