This textbook explains the concept of "object-based programming" as an essential part of "object orientation" and elucidates why the programming language Go, developed at Google, optimally supports this concept. Using significant parts of the micro-universe, a large collection of software components (with source code totaling nearly 64,000 lines), many important data types and their algorithms are described. In the practical section, various programs constructed according to this concept are presented. The translation was done with the help of artificial intelligence. A subsequent human revision was done primarily in terms of content.
