Jatkokehys

Jatkokehys is a Finnish term that translates to "extended frame" or "continuing framework." It is primarily used in the context of computer programming and software development, referring to a programming construct or pattern that allows for the extension or modification of existing code's behavior without altering the original source code. This concept is closely related to principles of modularity, extensibility, and open/closed design, aiming to promote maintainable and adaptable software systems.

The core idea behind jatkokehys is to separate concerns and allow for new functionality to be added or existing functionality to be customized in a non-intrusive manner. This can be achieved through various mechanisms depending on the programming language and specific implementation. For instance, in object-oriented programming, it might involve inheritance, composition, or design patterns like Decorator or Strategy. In more functional programming paradigms, it could involve higher-order functions or other techniques that allow for the manipulation of code as data.

The benefits of employing a jatkokehys approach include enhanced reusability of code, easier maintenance and debugging, and the ability to adapt software to changing requirements over time. It promotes a more flexible software architecture, reducing the likelihood of introducing errors when modifying or extending existing features. This approach is particularly valuable in large-scale projects or systems where the codebase is expected to evolve significantly throughout its lifecycle.
