Descriere
Have you ever encountered source code is difficult to read? Where you spend a lot of time trying to understand what the developer wanted to express in that particular code fragment.In this training we’ll show you how to not become that developer. You will learn about code smells, why and where they appear, and what techniques are used to remove them. We’ll start from simple problems in a single function and end with problems of communication between classes. We will also discuss what should and what should not be done to make your code easy to read.
