Go 101

Go 101 is a book focusing on Go syntax/semantics (except custom generics related) and all kinds of runtime related things (Go 1.19 ready) and tries to help gophers gain a deep and thorough understanding of Go. This book also collects many details of Go and in Go programming. Many of these details could not be found in official Go documentations. It is expected that this book is helpful for both beginner and experienced Go programmers.
