Why does Go require explicit error handling instead of exceptions?

Asked on Nov 02, 2025

Answer

Go requires explicit error handling to promote clarity and simplicity in code, aligning with its philosophy of explicitness and straightforwardness. Unlike exceptions, which can lead to hidden control flow paths, Go's approach ensures that errors are handled where they occur, making the code more predictable and easier to maintain.

Example Concept: Go uses explicit error handling by returning errors as values from functions. This approach encourages developers to handle errors immediately after a function call, reducing the risk of unhandled exceptions and improving code readability. By avoiding exceptions, Go maintains a clear and consistent control flow, which is easier to follow and debug.

Additional Comment:

Go functions typically return an error as the last return value, which should be checked immediately.
This pattern encourages developers to think about error handling as part of the normal control flow.
Explicit error handling in Go can lead to more verbose code but improves robustness and maintainability.
Go's error handling is designed to be simple and efficient, avoiding the overhead of exception handling mechanisms.
