== Go (programming language) ==

'''Go''' (often referred to as '''Golang''') is a [[compiled]] [[statically typed]] [[programming language]] designed at [[Google]] by [[Robert Griesemer]], [[Rob Pike]], and [[Ken Thompson]]. It was publicly announced in November 2009 and became open source in 2012. Go is known for its simplicity, fast compilation, built-in concurrency support, and efficient garbage collection.

The language's syntax is derived from [[C (programming language)|C]], but with many modernizations: no unnecessary parentheses in control structures, limited pointer arithmetic, and a strong emphasis on readability. Go also uses interfaces (implicit satisfaction) and embedded types (composition over inheritance) as its primary mechanisms for code reuse.

Go is widely used for building [[web server]]s, [[API]]s, cloud services, networking tools, [[command-line interface]]s, and microservices. Notable projects written in Go include [[Docker]], [[Kubernetes]], [[Terraform (software)|Terraform]], and the [[Hugo (software)|Hugo]] static site generator.

== Features ==

* '''Goroutines''': lightweight threads managed by the Go runtime, enabling efficient concurrent execution.
* '''Channels''': typed conduits for communication between goroutines, following [[CSP]] (Communicating Sequential Processes) style.
* '''Fast compilation''': the compiler can build large projects in seconds, facilitating rapid development cycles.
* '''Garbage collection''': automatic memory management with low latency, suitable for high-throughput services.
* '''Standard library''': extensive built-in packages for [[HTTP]], [[I/O]], [[encoding]], [[cryptography]], and more.
* '''Cross-platform support''': compiles to native binaries for [[Windows]], [[Linux]], [[macOS]], and many other platforms.

== History ==

Go was conceived in 2007 at Google to address frustrations with existing languages: slow compilation, lack of concurrency support, and complexity. Design goals included efficiency, speed of development, and ease of use. The first version (1.0) was released in March 2012, establishing a strong backwards compatibility promise.

Since then, Go has evolved steadily. Version 1.5 introduced a bootstrapping compiler written in Go itself. Version 1.11 added modules for dependency management. Version 1.18 (2022) added generics, a long-requested feature. The language is governed by the Go community under a permissive [[BSD license]].
