2,484 PointsHow can I transfer the value of an hash to an new variable?
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" } if grocery_item.has_value?("Bread") grocery_item.store("food", true) end
grocery_item.values_at("item")
This array variable from the "item" key shall I store in a new variable called grocery_list
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
if grocery_item.has_value?("Bread")
grocery_item.store("food", true)
end
grocery_item.values_at("item")
grocery_list << grocery_item.values_at("item")
grocery_list.store.values_at("item")

231,275 PointsThe instructions tell you how to get the value: "Use the values_at
method on the grocery_item hash ..."
The "store" part can be done with a simple assignment ("grocery_list = ...
").
