Derived Properties
Derived properties are computed or calculated attributes in software development that are not stored directly but are derived from other data or properties. They are commonly used in object-oriented programming, data modeling, and reactive systems to encapsulate logic and maintain data consistency. This concept helps reduce redundancy and ensures that values are always up-to-date based on their dependencies.
Developers should use derived properties when they need to compute values on-the-fly from existing data, such as calculating a total price from items in a shopping cart or formatting a display name from first and last names. It is essential in scenarios where data changes frequently, as it avoids storing redundant information and simplifies updates, making code more maintainable and less error-prone.
