Go is a programming language developed at Google by Robert Griesemer, Rob Pike, and Ken Thompson. In many ways, Go is similar to C, but with memory safety, garbage collection, and structural typing. Go first appeared in 2009, and has recently gained popularity, primarily for the development of microservices.
