Related introduction:

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, 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 "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).
