Use the functions in the standard library's log package to output error information. Bellow, registeruser returns a value of type error by calling errors.new: Go error using new () function. Golang errors package has a function called new () which can be used to create errors easily. In go, we can use the new() function to handle. Go’s approach makes it easy to see which functions return errors and to handle them using the same language constructs employed for. Tackling errors in go requires a different approach than the conventional methods in other mainstream programming languages, like javascript, which uses the try.catch statement, or python with its try… except block.
