Method returns with hashes and arrays.

I feel like I should be writing more code, but I'm not sure. Here is the instructions (I'm on step 1):

"Modify the "create_shopping_list" method to return a hash with the following keys and values: 'title': A string with the value "Grocery List" 'items': An empty array"

shopping_list.rb
def create_shopping_list
  puts "Title: " + "Grocery List"
  puts "Items: " + [].to_s
end

Caleb,

Remember that create_shopping_list method should return a Hash.

def create_shopping_list
  # hashes are created with brackets {}. E.G: new_hash = {} 
  hash = { 
    "title" => "Grocery List", # this is a key / value pair. In this case, "title" is the key and "Grocery List" is the value
    "items" => []  # the key 'item' is an empty array.
  }
end

Also, you can use numbers and symbols as the key.

new_hash = {
  1 => "This is a value",
  :name => "Jose" # :name is a symbol.
}

Read this to understand Hashes better.
