What language is golang?

Go (also known as Golang) is a statically strongly typed, compiled, concurrent programming language with garbage collection capabilities developed by Google.

Robert Griesemer, Rob Pike and Ken Thompson began designing Go in September 2007, and later Ian Lance Taylor and Russ Cox joined the project.                                                                                                                                                                                                                                                    (Recommended learning: go)

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).

Description

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.

Go 2.0 version will support generics, but has a negative attitude towards the existence of assertions, and also defends itself for not providing type inheritance.

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

Writing style

There are several regulations in Go, and these are mandatory. When the following regulations are not matched, compilation will generate an error.

There is no need to write a semicolon (;) after each line of the program.

Braces ({) cannot be placed on new lines.

If judgments and for loops do not need to be wrapped in parentheses.

Go also has a built-in gofmt tool, which can automatically sort out excess whitespace in the code, align variable names, and convert aligned spaces into tabs.
