git clone https://github.com/golang/goGo (often referred to as golang) is a programming language created at Google in 2009 by Robert Griesemer, Rob Pike, and Ken Thompson. It is a compiled, statically typed language in the tradition of Algol and C, with garbage collection, limited structural typing, memory safety features and CSP-style concurrent programming features added. The compiler and other language tools originally developed by Google are all free and open source.. Read more on Wikipedia...
