How to write clean code units (functions and methods) - Clean code and programming principles
In this video we examine how to write good code units (functions and methods) in your application. We start by looking at "edge" code units. Those are units that don't call any other functions when they run. Then, we generalise the concepts to all code units. Finally, we link those concepts back to the programming principles and writing good code in general.
