Go is an open source programming language created in 2007 by three Google engineers: Robert Griesemer, Rob Pike, and Ken Thompson. It was initially positioned as a modern systems language but has gained popularity for its elegant concurrency model, simple binary deployments, low number of external dependencies, fast performance, and runtime efficiency. A creative community of Go developers, known as "Gophers," has grown up around the language, with numerous conferences, organizations, schools, newsletters, blogs, podcasts, an online avatar generator, and a group for LGBT Gophers. Many knowledgeable experts in the field are worth following online for guidance on learning more about this programming language.
