Description: The ‘protected’ access modifier in TypeScript is a feature that allows controlling the visibility of class members. By declaring a member as ‘protected’, it ensures that it can only be accessed within the class itself and in subclasses that inherit from it. This is particularly useful in object-oriented programming, where the goal is to encapsulate logic and protect data from unauthorized access. Unlike ‘public’ members, which are accessible from anywhere in the code, and ‘private’ members, which are only accessible within the class itself, ‘protected’ offers a balance that allows subclasses to access members without exposing them to the rest of the program. This approach encourages code reuse and the creation of more robust class hierarchies, facilitating the extension and modification of functionalities without compromising the integrity of the base class. In summary, ‘protected’ is a modifier that plays a crucial role in encapsulation and inheritance, allowing for cleaner and more maintainable designs in TypeScript applications.
