If you’re curious about Google’s Go language but haven’t moved past “hello world” you might be interested in playing with the new interactive introduction to Go, A Tour of Go:
The tour is interactive. Click the Compile button now (or type Shift-Enter) to compile and run the program on a remote server. The result is displayed below the code.
These example programs demonstrate different aspects of Go. The programs in the tour are meant to be starting points for your own experimentation.
There’s also a long list of blog articles looking at the Go syntax. Jon Cooper recently wrote an article exploring the syntax of Go and Ruby by comparing a script written in both. Personally, I’m a huge fan of Ruby syntax so I still have a way to go in order to I warm up to the Go syntax.
