what is go-mastery fr?

GO Mastery is a personal knowledge base documenting the author's journey to learn the Go programming language in depth. Rather than a scattered pile of code snippets, it is organized as a structured set of lessons meant to build a complete mental model of Go, from basic computer science fundamentals up through production grade software concepts. The philosophy behind the project is that truly understanding a language means going beyond how to use it. For each topic the author tries to explain what it is, why it exists, the problem it solves, how it works internally, its memory and runtime behavior, common mistakes, best practices, performance implications, and how it connects to other concepts, instead of just memorizing syntax. The repository is organized into numbered sections covering computer science fundamentals, Go introduction and tooling, basic syntax, control flow, functions, composite types, methods and interfaces, and more topics beyond that. Each lesson inside those sections follows the same consistent format: a definition, background, mental model, internal implementation notes, diagrams, syntax, simple and real world examples, common mistakes, best practices, performance notes, related concepts, comparisons, frequently asked questions, exercises, a small project, a summary, and challenge questions. This is meant as a reference for developers learning Go from scratch, developers coming from another language, people preparing for technical interviews, or anyone who wants a deeper understanding of how Go works under the hood. It is an ongoing, continually updated project, and the author welcomes issues or pull requests pointing out errors or suggesting improvements. The project is released under the MIT License.
