I suspect that the author would argue that more competent programmers would use their IDE's statement completion functionality to quickly determine the function name, or which of the functions to use, what arguments to pass, and what return value type to expect and how to use it. That their knowledge of the language would allow them to write the code faster and better which such tools, rather than copying something from the internet.
