p-timeout adds a timeout to any promise. If the promise doesn't resolve or reject within the specified timeframe, it rejects with a TimeoutError. This is crucial for preventing stalled operations and ensuring application responsiveness. The package offers clean cancellation of the underlying promise, preventing resource leaks. Options allow customization of the error message and specifying a custom fallback value or promise to be used if the timeout occurs, increasing flexibility in handling timed-out operations.
