Each tutorial contains minimum amount of code and text needed to explain specific functionality. Such simple examples allow full understanding of the functionality without any unnecessary distractions. This approach allows students to grasp presented concepts in a fast and efficient manner.
Theoretical Background
Where needed tutorials are preceded by chapters focusing on theoretical background. This way reader can fully understand functionalities explained in the subsequent chapters. But such chapters are in minority and of secondary importance because the main focus is on code examples.
