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!

Learn Ruby from Scratch

There are a few more objects to mention that we’ll see quite frequently. First are `true` and `false`.


## The `true` and `false` objects
The true and false objects are rather straightforward: the true object represents truth, while false represents the opposite.


In other words, `true` and `false` are also things, just like the examples of numbers and strings we saw earlier. We can assign them to variables, pass them around, and use them in other ways. They’re fairly simple but useful.
