 Go 是一门用于并发编程的命令式编程语言，它主要由创造者 Google 进行开发，最初主要由 Robert Griesemer、Rob Pike 和 Ken Thompson开发。这门语言的设计起始于 2017 年，并在 2019 年推出最初版本；而第一个稳定版本是 2012 年发布的 1.0。
 
-Go 有 C 风格语法（没有预处理器），垃圾回收机制，并且类似它在贝尔实验室里被开发出来的前辈们，Newsqueak (Rob Pike)、Alef (Phil Winterbottom) 和 Inferno (Pike, Ritchie, et al.)，使用所谓的 goroutines 和 channels（一种基于 Hoare 的“通信顺序进程”理论的协程）提供内建的并发支持。

-Go programs are organised in packages. A package is essentially a directory containing Go files. All files in a package share the same namespace, and there are two visibilities for symbols in a package: Symbols starting with an upper case character are visible to other packages, others are private to the package:

 ### 类型
 
-Go has a fairly simple type system: There is no subtyping (but there are conversions), no generics, no polymorphic functions, and there are only a few basic categories of types:
+Go 有一个相当简单的类型系统：没有子类型（但有类型转换），没有泛型，没有多态函数，只有一些基本的类型：

-type T *T

+      type T struct { foo int }
+      type T *T
+      type T OtherNamedType
+      ```
 
-Named types are mostly distinct from their underlying types, so you cannot assign them to each other, but some operators like `+` do work on objects of named types with an underlying numerical type (so you could add two `T` in the example above).

 Maps, slices, and channels are reference-like types - they essentially are structs containing pointers. Other types are passed by value (copied), including arrays (which have a fixed length and are copied).
