Unused global variable

Reports global variables that are defined but are never used in code.

If you have unused variables, the code will not compile. For more information about unused variables and imports, refer to Unused imports and variables at go.dev.

func main() { a := 422 }

Code in the example will not compile. Therefore, it is highlighted as an error. You can apply two quick-fixes for such cases: Delete variable and Rename to _. The first quick-fix deletes the variable, the second one will convert the variable to a blank identifier.

After the Rename to _ quick-fix is applied:

func main() { _ := 422 }
