Replica of Ruby's Array#each method. Appropriately dubbed "my_each"... :) Throwing in my_collect for shits and giggles.

my_each.rb

class Array

  def my_each
    i = 0
    while i < self.length
      yield(self[i])
      i += 1
    end
    self
  end
  
  def my_collect
    results = []
    self.my_each do |i|
      results << yield(i)
    end
    results
  end
  
end
