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 =  end def push(item) array.push(item) end def each(&block) i = 0 while i < array.length block.call(array[i]) i += 1 end array end end
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.
