Hook

A hook is a programming feature that allows developers to "tap into" or modify the behavior of existing code at specific points during execution. Think of it as a signal or trigger that lets you insert custom actions or change how a program works without altering its core structure. Hooks are commonly used in systems like content management or software frameworks to enable flexibility, customization, and extension by attaching functions that run when certain events or conditions occur. This approach promotes modularity and easier updates, allowing new features or behaviors to be added seamlessly.
