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 enjoy writing Go for its simple, minimalist syntax. Mentoring in Go is a joy, thanks to its opinionated nature ('The Go Way'). I write and review Go professionally, as well as in side projects.

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.
