Ruby Ruby Collections Ruby Hashes Working with Hash Keys

I'm not sure what's going on here

hash = { "name" => "Bread", "quantity" => 1, "calories" => 100} hash.has_key?("calories") food = true

hash = { "name" => "Bread", "quantity" => 1, "calories" => 100}
food = true

in the first line you are creating a hash, it is a proper hash and would return true. on the second line you are asking if the hash has a key called "calories". The hash does have this key, so it would return true. on the last line you're assigning a variable called food to be equal to true. this would return true.
