Pointcuts

Pointcuts are tools used in software development, specifically in Aspect-Oriented Programming, to identify specific points in a program's execution where additional actions can be inserted. Think of them as filters or selectors that capture particular moments—like when a function is called or completed. These points allow developers to add cross-cutting concerns such as logging, security checks, or timing without changing the core code, making the program more modular and maintainable. Essentially, pointcuts specify *where* in the program the extra behaviors should be applied.
