go-rock-libraries-showcases hosts the materials for Go, an advanced tutorial series focused on well-known Go third-party libraries. It is designed for learners who have already finished Go, and want to deepen their skills by exploring real-world libraries that are popular and highly regarded in the Go ecosystem. The course uses a “three-in-one” approach: blog posts, code examples, and audio/video lectures are combined to explain each library in practical context.
