Detailed introduction:

Go (also known as Golang) is a static strong type developed by Google , compiled, concurrent, and garbage-collected programming language.

Robert Griesemer, Rob Pike and Ken Thompson started designing Go in September 2007, and later Ian Lance Taylor, Russ Cox joins the project. Go is developed based on the Inferno operating system. Go was officially announced in November 2009, becoming an open source project and implemented on Linux and Mac OS X platforms, and later added implementation under Windows systems. In 2016, Go was selected as the "TIOBE Best Language of 2016" by the software evaluation company TIOBE. Currently, Go releases a second-level version every six months (that is, upgrading from a.x to a.y).

Go's syntax is close to C language, but the declaration of variables is different. Go supports garbage collection. Go's parallel model is based on Tony Hall's Communicating Sequential Process (CSP). Other languages ​​that adopt a similar model include Occam and Limbo, but it also has features of Pi operations, such as channel transmission. Plugin support is opened in version 1.8, which means that some functions can now be dynamically loaded from Go.

Compared with C, Go does not include functions such as enumeration, exception handling, inheritance, generics, assertions, virtual functions, etc., but it adds slice type, concurrency, pipes, garbage collection, Language-level support for features such as interfaces. The Go 2.0 version will support generics, but has a negative attitude towards the existence of assertions, and also defends that it does not provide type inheritance.

Unlike Java, Go has built-in associative arrays (also known as hash tables (Hashes) or dictionaries (Dictionaries)), just like string types.
