Ruby Ruby Blocks Working With Blocks Implementing Block Methods

Why is 'array' needed on line 17?

Perhaps I overlooked the explanation in the lecture. Is it related to the scope of the 'array' variable?

class MyArray
  attr_reader :array
  def initialize
    @array = []

  def push(item)

  def each(&block)
    i = 0
    while i < array.length
      i += 1

Hi Barb, the standard each method returns the original array so to replicate that functionality, the word array is added on line 17 as an implicit return of the original array.
