👉 Listable is a term used in computer science and software engineering that refers to a property of an object that allows it to be easily added, removed, or modified. This means that when an instance of a class is created, its attributes (like name, age, etc.) can be set to values that are easy to manipulate by other instances of the same class. Listables allow for efficient and flexible data manipulation in software applications, as they make it easier to add new features or modify existing ones
