7,246 PointsWhy is my solution wrong\bad?
Add the grocery_item hash to the items array inside of the grocery_list hash.
grocery_list = { 'title' => 'Grocery List', 'items' => [] }
grocery_item = { 'title' => 'Bread', 'quantity' => 1 }
my solution
grocery_item = { 'title' => 'Bread', 'quantity' => 1 }
grocery_list = { 'title' => 'Grocery List', 'items' => [grocery_item] }
solution that I found when I was in doubt that mine is proper
grocery_list = { 'title' => 'Grocery List', 'items' => [] }
grocery_item = { 'title' => 'Bread', 'quantity' => 1 }
grocery_list['items'].push(grocery_item)
The question is - why my solution is bad or wrong? Or it's just differs?
grocery_list = { 'title' => 'Grocery List', 'items' => [] }
grocery_item = { 'title' => 'Bread', 'quantity' => 1 }

18,132 PointsThe result of your solution and the .push solution is the same, but your way is less 'elegant', because you are asigning again the grocery_list variable, on the other side the 'good' solution just modifies the variable, pushing a hash inside the 'items' array.
What if 'item' weren't an empty array? Then your solution could not work because you could be overwriting content. push is a nice solution because you just add an item to the array, without deleting previous content.
