If you already know some of the fundamentals of the Ruby language, but you want to get some hands-on experience to expand your skills, I suggest taking a look at the following tools/platforms:

- [**Ruby Koans**](https://www.rubykoans.com/?ref=jvrc.ca) \- Learn the Ruby language, syntax, structure, and some common functions and libraries. You’ll also learn about culture and testing.
