Go, or Golang, is a programming language developed by Google in 2007 aimed at enhancing software development efficiency and scalability. It features a simple syntax, is statically typed, and supports systems, web services, and concurrent programming. Popular users of Go include companies like Google, Docker, and DigitalOcean, with numerous resources available for learning the language.
Intro to Go

- 2. What is Go? • Programming language developed at Google in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson • Compiled, Statically-Typed language with “C”-like syntax • Designed to be a simple language to learn • Addresses real scalability and productivity problems at Google • Developed because the inventors disliked C++ ;) Image credits: http://talks.golang.org/2012/splash/datacenter.jpg
- 3. Why Go? (in quotes) “The goals of the Go project were to eliminate the slowness and clumsiness of software development at Google…” “The language was designed by and for people who write and read and debug and maintain large software systems.” “Go's purpose is therefore not to do research into programming language design…” “Less is exponentially more” Excerpts from: http://talks.golang.org/2012/splash.article, http://commandcenter.blogspot.com.au/2012/06/less-is-exponentially-more.html Image credit: http://rouninurashima.files.wordpress.com/2012/05/gordon_unicorn1.png
- 4. What is it good for? • Systems Programming - like C but easier, low-level access, C-interop • Web Services - It has just about everything you need built into the Standard Library • Concurrent Programming - Its built into the language: goroutines and channels • Target multiple platforms - Linux, Windows, Mac OS X, Free BSD • Simple deployments - Your app is a single binary with no other dependencies • Large scale development! • Easy to read, write, maintain • Garbage collected, statically-typed, fast compilation, fast execution Image credit: http://blog.golang.org/go-11-is-released_gopherbiplane5.jpg
