Become manner. So this article will use the interview manner to make descriptions instead. Hi Tapir, when and why did you plan to write this book? At about July 2016, after (not very intensively) using Go for two seldom languages own the four characteristics at the same time. In fact, this is the main reason why I switched to Go from Java for web development. Built-in concurrent programming support is also a
