Is it necessary to always use the Cancel method when creating a context with a timeout via Context.WithTimeout?

Yes, it is recommended to always call the Cancel function returned by context.WithTimeout to release resources associated with the context as soon as it is no longer needed. Even if the timeout occurs and the context is automatically canceled, calling Cancel helps prevent resource leaks.

Example usage:

ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()

// Use ctx in operations

Calling defer cancel() ensures that resources are released when exiting the function, even if the operation completes before the timeout.
