Learn the basics of Ruby with hands-on practice.

Become a Ruby Professional

Do you want to be an interpreted language geek? Are you tired of getting entangled in the dense syntaxes? Does it irritate you to compile your code to machine language first? Are you looking for an easy-to-use scripting language? Well, Ruby is the best pick for you then!
This introductory module will be providing you with hands-on practice with the support of a bunch of interactive illustrations, exercises, and the integral topics of variables, built-in classes, objects, conditionals, blocks, and much more!
