8,185 PointsNot sure how to create a new variable inside the hash if the key? method = true.
I've tried plenty of different ways, I'm getting argument error. It's expecting 2 arguments and it's getting 1. Pleas help.
hash = { "name" => "Bread", "quantity" => 1, "calories" => 100 }
hash.key?("calories")
if true
hash.store("food")
end

if hash.has_key?("calories")
food = true
end

8,185 PointsFrom my understanding key? works the same way has_key? does. Also I suppose I was overthinking this challenge. Thank you for helping me understand this.
