Ruby Ruby Collections Ruby Hashes Working with Hash Keys

set new variable to true if hash key method `has_key` returns true

not sure what you all are looking for for the question "Using the has_key? method, check if the hash variable has a key called "calories". If it does, set a new variable called food to true." the code is as follows

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

but where i get confused is what you want with me setting a new variable of food to true, and how i should go about that. I tried

food == {"calories"=>100}

but that did not work.

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