Got a rainy Sunday afternoon and a taste for a porting puzzle?

• Get inspiration from Go strings documentation, Go strings source, Go strings examples source, GopherJS.
• Click "New file" in the appropriate folder on GitHub. This will fork the project to your account, directly add the file to it, and send a Pull Request to us.

We will then review it. If it's useful to the project and in line with our contributing guidelines your work will become part of Locutus and you'll be automatically credited in the authors section accordingly.
