Stored Properties
Stored properties are a core concept in object-oriented and class-based programming languages, where they are variables or constants that store values directly within an instance of a class or structure. They persist for the lifetime of the object and are used to represent the state or attributes of that object, such as a person's name or a car's speed. Unlike computed properties, which calculate values on the fly, stored properties hold data that is set and retrieved directly.
Developers should learn stored properties because they are fundamental for modeling real-world entities in code, enabling data encapsulation and state management in applications. They are essential in scenarios like creating user profiles, managing inventory items, or handling configuration settings, where persistent data needs to be associated with objects. Understanding stored properties is crucial for building robust, maintainable software in languages like Swift, Java, or C#.
