It was developed in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson at Google but launched in 2009 as an open-source programming language. Programs are assembled by using packages, for efficient management of dependencies. This language also supports environment adopting patterns alike to dynamic languages. For eg., type inference (y := 0 is a valid declaration of a variable y of type float).\n" +

+                "Go is known for its support for concurrency, which is the ability to run multiple tasks simultaneously. Concurrency is achieved in Go through the use of Goroutines and Channels, which allow you to write code that can run multiple operations at the same time. This makes Go an ideal choice for building high-performance and scalable network services, as well as for solving complex computational problems.";
