Tigraine Daniel Hoelbling-Inzko talks about programming Home Articles About me Why I love Go error handling One thing that Go almost forces you to do is to explicitly handle each and every error that any random part of the system might create. This has one very obvious side effect of making even simple code quite long and peppered with if err != nil statements: func writeFile() error { fileName := "test.txt" f, err := os.Open(fileName) if err != nil { return fmt.Errorf("failed to open file %s: %w", fileName, err) } defer f.Close() d1 := []byte("hello\ngo\n") _, err = f.Write(d1) if err != nil { return fmt.Errorf("unable to write to file %s: %w", fileName, err) } return nil } As you can see a simple open-file-and-write requires 2 error checks that add almost 50% of lines of code to this rather simple method. Because of this most Java/C#/C++ people you show Go code to almost always react with aversion and distaste and never give the language another chance (although I think this is now |
