What is the programming language go?

The programming language go refers to the Golang language, which is a statically strongly typed, compiled, concurrent programming language with garbage collection function developed by Google; the syntax of Go is close to the C language, but for variables The declaration is different, Go natively also provides associative arrays.

Go (also known as Golang) is a statically strongly typed, compiled, and A programming language with garbage collection capabilities.

Robert Grismo, Rob Pike, and Ken Thompson began designing Go in September 2007, and later Ian Lance Taylor and Russ Cox joined the project. Go is developed based on the Inferno operating system. Go was officially announced in November 2009 and became an open source project, supporting operating systems such as Linux, macOS, and Windows. In 2016, Go was selected as "TIOBE's 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 computing model is based on Tony Hall's Communicating Sequential Process (CSP). Other languages ​​that adopt similar models include Occam and Limbo. Go also has the characteristics of this model, such as channel transmission. Thread pools and pipelines can be built through parallel constructs such as goroutines and channels. 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, pipeline, and garbage collection functions. Language-level support for , interfaces and other features. 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 natively provides associative arrays (also known as hash tables (Hashes) or dictionaries (Dictionaries)).
