Having trouble with Ruby Hash Challenge 2 of 2

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

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

if grocery_item.has_value?("Bread")
  grocery_item["food"] = true
end 

grocery_list = { grocery_item.values_at("item") }

Not sure why I'm getting an error message on this one.

The values_at method will automatically create a new hash. So there is no need to have { } around it's output.

Wouldn't the values.at method create an Array?

Either way removing the {} is the right answer.

this works fine

if grocery_item.has_value?("Bread") grocery_item["food"] = true end

grocery_list = grocery_item.values_at("item")

HI I am confused with array? how come we're not using [] , and we're using values_at("item").

Bellow is the code I used it worked but I am confused with the logic I guess

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

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

grocery_list = grocery_item.values_at("item")
