Using the each method, iterate over the contact_list array. Assign each array item to the local variable contact in the block and print out the value of the name and phone_number keys.

contact_list = [
  {"name" => "Jason", "phone_number" => "123"},
  {"name" => "Nick", "phone_number" => "456"}

Using the each method, iterate over the contact_list array. Assign each array item to the local variable contact in the block and print out the value of the name and phone_number keys.

The code you wrote is an incomplete .each loop in Ruby.

contact_list = [
  {"name" => "Jason", "phone_number" => "123"},
  {"name" => "Nick", "phone_number" => "456"}
]

contact_list.each do |item|                       # item is the each hash contained within the contact_list Array
  contact = item                                  # Assign each array item to the local variable contact
  puts contact['name'], contact['phone_number']   # print out the value of the name and phone_number keys
end

See if the comments help you understand the logic of the each line of the code, Ask me if you have further question.

Thank you! Makes far more sense than how the course teaches, if it does at all...
