+**`Encodable`** is a protocol that enables a type's data to be encoded and for use with Application Programming Interfaces ([APIs](https://www.codecademy.com/resources/docs/general/api)). If data also needs to be decoded, it's convenient to use the `Codable` protocol because it includes both the `Encodable` and `Decodable` protocols.
