Three new books, Go Optimizations 101, Go Details & Tips 101 and Go Generics 101 are published now. It is most cost-effective to buy all of them through this book bundle in the Leanpub book store.


Some of the details and tips in this book are collected from the Internet, some ones are found by myself. I will try to list the source of a detail if it is possible. But I'm sorry that it is impossible task to do this for every detail.
