Using the values_at method, create an array called grocery_list with the value of the grocery_item hash at the"item" key

I came up with this:

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }

if grocery_item.has_value?("Bread")
  grocery_item.store("food",  true)
  grocery_item.values_at( "item" => grocery_list)
end
hash.rb 
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }

if grocery_item.has_value?("Bread")
  grocery_item.store("food",  true)
  grocery_list.values_at( "item" => grocery_item)
end

Hi Sy Loc,

Actually you need to create new array "grocery_list" outside the if statement. The value_at method given by question challenge is to find key "item" inside grocery_item from the first line. Your code example is more like new key and value pairs way is not correct but very close you got it almost.

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }

if grocery_item.has_value?("Bread")
  grocery_item.store("food",  true)
end

#Example
grocery_list = grocery_item.values_at("item")

Hope that helps. :)

Thank you Salman for the explanation, I can't seem to get these stuff. Totally misread it, I suppose to 'create new array'.
