Go Tutorial

Welcome to Go Language (GoLang) Tutorial. In this tutorial, we learn what Go language is, its features, and list out the tutorials covering basics, conditional and looping statements, collections, etc.

“Go” and “Golang” are used interchangeably in this and subsequent tutorials.

What is Go Language?

Go is a programming language initially developed at Google in the year 2007 by Robert Griesemer, Rob Pike, and Ken Thompson.

Go language provides a rich standard library. The Go programming language is used in some of Google’s production systems and also in many other major companies.

Resemblance with other languages

Go is a statically-typed language having the syntax similar to that of C.

Go Features

Go language provides

  • Garbage Collection
  • Type Safety
  • Dynamic-typing capability

and many advanced built-in types such as variable length arrays and key-value maps.
