About this course

Learn Ruby Programming online

Ruby is known for readable, expressive code and is the language behind the Rails web framework. It treats everything as an object, which is elegant but surprising if you are used to other languages, and learners often find blocks, symbols and modules confusing at first.

This course follows the standard Ruby curriculum from the official documentation: basics, control flow, methods, strings, arrays and hashes, blocks and iterators, classes and objects, modules and mixins, error handling and files, and testing. Each module lists topics and what you will be able to do at the end.

Learn with an affordable 1:1 mentor who explains each idea with short examples and reviews your code with you. Self-study lessons on MentorNxt exist only for Java and Python, so this course is taught in live 1:1 sessions. Message us on WhatsApp or email, or fill in the short form, for a free, no-obligation chat. We will suggest a plan that fits your budget and flexible timings, and you can start this week.

FAQs

Ruby Programming: frequently asked questions

Is there a self-study option for Ruby Programming?

Not yet. MentorNxt's free self-study lessons cover Java and Python only, so Ruby Programming is taught through 1:1 mentoring. Your mentor plans sessions around your goals, explains with fresh examples and reviews your code with you.

Do I need to learn Ruby before Rails?

It is strongly recommended. Rails is written in Ruby, and understanding blocks, classes and modules makes Rails much easier to follow.

Is Ruby a good first language?

Yes. Its syntax is readable and forgiving, which makes it comfortable for beginners. Your mentor will explain the ideas that are unusual, like blocks and everything being an object.

Which Ruby version do you teach?

Ruby 3 and later, the versions used in current projects. Your mentor will note differences if your course uses an older version.
