What is wrong with this code? It seem right to me.

I cannot seem to understand why I keep getting errors on this one.

shopping_list.rb
def create_shopping_list
  hash = ('title' => "Grocery List", 'items' => [])
  return hash 
end

Hi Daniel,

Ruby doesn't use brackets ( ), when we are assigning a variable to create hashes, then it is { }

def create_shopping_list
  hash = { 'title' => "Grocery List", 'items' => [] }
  return hash 
end

#or 

def create_shopping_list
  hash = { 
         'title' => "Grocery List", 
         'items' => [] 
          }
  return hash 
end

Hope that helps.

in order to that you also can do it the safe way:

def create_shopping_list
  hash = { 'title' => "Grocery List", 'items' => Array.new }
  return hash
end
            ```
