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 started go 4 years ago, using it professionally and personally. Explaining to others is the best way to make sure you understand, they said!

Go is the first compiled langauge that I was comfortable with. It is also the first langauge I wrote production worthy code in.
Fun. Challenging. Interesting
