Returning Boolean Literals

This is a bad code example when a function returns boolean values with if else checking. Boolean is a binary results. Hence, a lot of languages offers return with comparison features.

Bad Codes

Here is an example of bad codes:

func IsRoot() bool {

        id := os.Getuid()

        if id <= 0 {

                return true

        }

        return false

}

Better Codes

From the bad codes, we can actually compare the condition straight with the function and return the end result. Hence, the function should be:

func IsRoot() bool {

        return os.Getuid() <= 0

}

One line, crisp and clear.

That's all about bad returning Boolean literal codes.
