Codable protocol

The Codable protocol in programming is a way for a data model to automatically convert itself to and from a format suitable for storage or transmission, like JSON. It combines two capabilities: encoding (turning an object into data) and decoding (building an object from data). When a data structure conforms to Codable, it can easily be saved, sent over a network, or received, without needing to write complex custom code. This makes handling data more straightforward, reliable, and less error-prone in software development.
