👉 Focusability in software development refers to a property of objects that allows them to be "focused" on specific aspects or elements. This is often achieved through encapsulation, which involves hiding complex data and methods from external access, allowing only those necessary for the task at hand to be accessed. By focusing on a subset of the object's properties or methods, developers can create more modular and maintainable codebases by reducing the amount of data they need to manage and potentially improving performance as well.
