Learn Ruby: 3 Fun & Free Interactive Resources
Exploring the Ruby Programming Language
Ruby is a dynamic, highly readable, and versatile scripting language. While frequently employed within the Ruby on Rails web development framework, it also functions effectively as a standalone programming tool.
For those interested in experiencing Ruby – distinct from Ruby on Rails – a dedicated learning resource isn't always immediately necessary.
Instant Ruby Access: Browser-Based Options
There are several engaging and straightforward methods to experiment with Ruby directly within your web browser. These options allow you to begin coding immediately, completely free of charge, and without requiring any software installation.
Here are three convenient ways to get started:
- TryRuby: This interactive tutorial provides a guided introduction to the core concepts of Ruby.
- Repl.it: A powerful online IDE supporting numerous languages, including Ruby, offering a full development environment.
- CodePen: Primarily known for front-end development, CodePen also supports Ruby, allowing for quick experimentation and sharing of code snippets.
These browser-based tools offer a risk-free and accessible entry point into the world of Ruby programming. They are ideal for beginners and experienced developers alike who wish to quickly test ideas or learn the language's fundamentals.
Rubymonk
Originating in India, Rubymonk provides a collection of over 50 concise, interactive Ruby programming exercises, with the added benefit of progress saving.
The image above illustrates the interface encountered upon returning to the Rubymonk website after a period of inactivity, having previously completed the initial exercises.
Exercise Structure
Let's examine the format of a typical exercise. Each one begins with a straightforward explanation of the concept being taught.
This is followed by a code snippet for demonstration. Executing the code via the 'Run' button provides immediate feedback through the displayed output.
Subsequently, a task is presented to the learner. The challenge involves writing code to achieve a specific outcome, and submission is accomplished by pressing Ctrl+Enter or clicking the 'Run' button.
Rubymonk then evaluates the submitted code and presents the result.
Independent Problem Solving
As you progress through the exercises, you will encounter problems designed to be solved independently.
These problems include a clear description of the required solution, along with starter code to facilitate the process. Should you become stuck, the option to reveal the solution by clicking “See the Solution” is readily available.
Navigating the Curriculum
Upon completing initial exercises, users are directed to a table of contents.
This allows for the selection of specific learning topics, with a choice between lessons and problems.
Lesson and Problem Formats
Lessons are designed to impart knowledge and skills. They appear as shown in the accompanying image.
Problems, conversely, challenge the learner to apply their understanding. Their appearance is illustrated in the following image.
The 'tags' indicate lessons that should be completed sequentially to build the necessary skills for tackling the associated problems. The platform is remarkably well-designed and offers an enjoyable learning experience. It comes with a strong recommendation.
Ruby Koans [Currently Unavailable]
The Ruby Koans are now located on the Heroku platform, presenting a learning experience even more focused on abstract thought than Rubymonk. You can explore them here:
Regardless of personal preference, this resource offers a distinctly engaging approach to learning. Users are prompted to provide their anticipated solution, even for seemingly simple problems, and then submit their answer.
The code is then evaluated, and the result is visually indicated. Ruby Koans provide a highly enjoyable learning path, appearing to be more sophisticated than Rubymonk in its initial approach.
Key Features and Considerations
- The learning process begins with asserts and testing methodologies.
- Unlike Rubymonk, the focus isn't immediately on fundamental concepts like arrays.
- A notable drawback is the lack of automatic progress saving.
Therefore, it is advisable to bookmark your current position within the koans to avoid losing your place. While not as dynamically updated as Rubymonk, it remains a valuable resource.
This project has served as a source of inspiration for numerous similar learning tools, including the JavaScript Koans.
Explore Ruby Programming
Try Ruby was developed as an homage to "why's (poignant) guide to ruby," a uniquely engaging programming textbook. It stands out as one of the most unconventional learning resources I’ve encountered.
This resource is highly regarded for its approach to the Ruby language. Despite the original author’s reduced involvement in the Ruby community, it’s likely the project would have garnered their approval.
Interactive Learning Environment
The website is designed to mimic a Ruby command-line interface, accompanied by clear instructions. This provides a hands-on learning experience.
The presented text is straightforward and approachable, avoiding complex or esoteric references. Users directly input Ruby code into the prompt.
Progress is made through a series of uncomplicated exercises, completed sequentially. The entire learning process is designed to be relatively quick to finish.
Key Features
- Real Ruby Code: You are writing and executing actual Ruby syntax.
- Step-by-Step Exercises: Learning is broken down into manageable steps.
- Playful Approach: The tone is lighthearted and encourages experimentation.
Concluding Remarks
In my opinion, practical application is a highly effective method for grasping new concepts. While these exercises may not instantly transform you into an expert Ruby programmer, they will undoubtedly provide valuable hands-on experience with the language.
Should you be interested in exploring Ruby, I recommend selecting a resource that appeals to you and experimenting with it. We encourage you to share your experiences and insights in the comments section below.
