内容简介
Go编程语言，通常也称为Golang(尽管这种叫法并不对)，借助一些大师级开发作品以及的编程思想的高屋建瓴，着实取得了长步。Shopify的执行官Tobias Lutke便声称“Go将成为未来的服务器语言”，掷地有声，雄心勃勃。 Go程序员的需求量正处于高位，但更有争议的是，Go走上了以前由C和Unix程序员的舞台。Go语言的成长使其能够实现系统、网络、Web以及云应用。只要熟悉了语法，掌握库的使用并利用其语言特、率，你将受益无穷，Go生态学正是因此而闻名。你多少已经知道了点Go语言的语法，也编写了一些小项目，而大多数Go程序员都面临着将Go语言技能与生产代码结合的难题。对Go编程的典型介绍往往是浅尝辄止，而作者将继续告诉你如何解决这个问题。本书提供了Go的概要，介绍了Go的实现，还有专门一章深入解释了并发、系统以及网络编程，这对于现代的原是必不可少的，读者也将从中受益。
