About Go

package greeting

// HelloWorld greets the world.
func HelloWorld() string {
	return "Hello, World!"
}

Fans of Go (called gophers) describe Go as having the expressiveness of dynamic languages like Python or Ruby, with the performance of compiled languages like C or C++.

The language is open source, and was started by engineers at Google. It's written using a C-style syntax, has statically typed variables, manages memory using garbage collection, and is compiled into stand-alone executables.

Go is noted for the concurrent programming features built into the language core, the networking packages in the standard library (such as a web server), fast compilation and execution speed. Its simple, minimalistic and consistent language design make for a delightful experience, while the abundant and thoughtful tooling addresses traditional problems such as consistent formatting and documentation.

The home page for Go is golang.org, and there is an excellent interactive tutorial at tour.golang.org.

Self-contained finite problems with which to learn the language

I have spent time with the Clojure, Elixir & Go tracks and all have been incredibly beneficial, providing self-contained finite problems with which to learn the language. The Go language track has been wonderful in introducing me to the language, what idiomatic code is, and the many different ways in which one can solve a problem.

Relaxed. Encouraging. Supportive.

I like Go for its simplicity and single-binary deployment, it's a good fit for CLI tools and network servers.

I love teaching people how to learn new things and am learning Go myself, so I'd like to give back

Go is somewhat of a new language for me and I've been trying to learn more and more of it. I got a taste of it through reading some Docker code and I find it to be a better C, which was something I wrote in a past life.

I've come to love working in Gol and Python, and am always on the lookout for the next big thing to pickup. There is always something new to learn!

I only started learning Go about a year ago but I've quickly come to love it. I hope I can help you learn to love it too!
Fun. Challenging. Interesting

Firmware Engineer by day. I like Go a lot, and I'm optimistic about its adoption. Helping on Exercism track allows me to learn more. My focus is adding exercise solutions and test case generators.

Since early 2016 I'm a professional Go developer. I love it because it's so simple and yet so powerful. Before Go if have worked with a lot of other languages. At least one year of experience I have in Python, PHP, JavaScript and several Basic languages from QBasic to VB.Net.

I'm a Canadian (based in Chicago) golang, C and python developer working on projects within the gaming, finance and data-science worlds respectively. My favorite freetime task is coding challenges and I'm more than happy to help people talk through solutions!

Get started with the Go track. As with everything on Exercism, it's 100% free!
