Do you want to learn about interpreted languages? Tired of dense syntaxes? Tired of compiling code to machine language first? Are you looking for an easy-to-use scripting language? Well, Ruby is the answer!

Ruby is a smart, easy-to-use, functional, object-oriented programming language, a wondrous mix of Perl's scripting power, Pythonic capabilities, and more! As Matsumoto, creator of Ruby, implies: "I hope to see Ruby help every programmer in the world to be productive, and to enjoy programming, and to be happy. That is the primary purpose of Ruby language."

This introductory course provides hands-on practice with the support of interactive illustrations, exercises, and the integral topics of variables, built-in classes, objects, conditionals, blocks, and more!

Ready to dive into one of the most influential and demanding third-generation programming languages? Let's get started!

## Things coming to life

Programming is creation. Whenever a program is executed, a little universe is created. Things come to life and interact with each other according to the rules that are defined by the creators of the program.

Imagine you’re building an application like Twitter.
