Pointcut

A pointcut is a way programmers specify particular points in a software program’s execution where additional code, known as "advice," should be inserted. Think of it as a targeted highlight that marks specific moments, like before a function runs or after it finishes. This allows developers to add, modify, or monitor behavior (such as logging or security checks) without changing the original code directly. In essence, a pointcut defines *where* in the program the extra actions should happen, making code more modular and easier to manage.
