Error Handling: The Explicit Way

Go (Golang) for Cloud-Native Microservices

No Exceptions, Just Errors

Go encourages checking errors explicitly. This makes code predictable and reliable.

Creating Errors:

go errors.New("something went wrong") fmt.Errorf("user %d not found", id)

Handling Pattern:

go res, err := DoSomething() if err != nil { // Log and return/handle return err }

This "if err != nil" check will become muscle memory.
