A callback mechanism is a programming pattern where a function is passed as an argument to another function, allowing the latter to execute the former at a later point in time. This technique is widely used for asynchronous operations, enabling non-blocking execution and efficient resource management.

Asynchronous operations allow tasks to be executed independently of the main program flow, enabling applications to remain responsive while waiting for long-running tasks to complete. This approach is crucial for improving performance and user experience, especially in environments where I/O operations or network requests are involved.
