Why Learn Ruby in 2025?
In a world dominated by fast-paced technological innovation, choosing the right programming language to begin or advance your coding journey is more important than ever. Ruby continues to stand out—not because it’s the flashiest or the newest—but because of its elegant syntax, object-oriented foundation, and developer-friendly ecosystem. This article by CoderTutorial is designed to introduce you to Ruby’s core principles through a practical and engaging. Ruby tutorial, with the goal of helping you write cleaner code, faster.
Whether you're completely new to programming or a seasoned developer exploring new languages, this tutorial will walk you through Ruby’s unique strengths and how it can empower you to build powerful, readable, and maintainable applications.
What is Ruby?
Ruby is a dynamic, open-source programming language that prioritizes simplicity and productivity. It was developed by Yukihiro “Matz” Matsumoto in the mid-1990s with a clear philosophy: programming should be fun for developers. This ethos has led to a language that reads like English and feels intuitive to write.
Inspired by languages like Perl, Smalltalk, Eiffel, and Lisp, Ruby brings the best of various programming paradigms together. Its syntax is elegant yet expressive, which makes it easier to understand and faster to learn—especially for beginners.
Getting Started: Your First Ruby Tutorial
Let’s jump into the heart of this guide: a practical Ruby tutorial for beginners.
Step 1: Setting Up Your Environment
Before writing your first Ruby program, you’ll need to install Ruby on your machine. Fortunately, Ruby is available on most operating systems:
-
macOS: Ruby comes pre-installed.
-
Windows: Use the RubyInstaller (https://rubyinstaller.org/).
-
Linux: Use your package manager (e.g.,
sudo apt install rubyon Ubuntu).
Once installed, open your terminal and type:
You should see the installed Ruby version, confirming it’s ready to use.
Step 2: Writing Your First Ruby Script
Open a text editor and write the following code:
Save the file as hello.rb, then run it in the terminal:
Output:
That’s it—you’ve just written your first Ruby program! Notice how clean and simple the syntax is—no semicolons, no class declarations, just straightforward code.
Step 3: Understanding Ruby’s Object-Oriented Nature
In Ruby, everything is an object—even numbers and strings. Let’s look at an example:
This means every value has built-in methods. For example:
Ruby's object-oriented nature allows developers to build modular, reusable code effortlessly. You can define your own classes and methods like this:
Step 4: Leveraging Mixins and Modules
Unlike other languages that rely heavily on inheritance, Ruby encourages composition through modules. Modules act as mix-ins that inject reusable behavior into classes:
This approach promotes cleaner and more maintainable code—ideal for larger applications.
Ruby on Rails: Ruby’s Killer Framework
No Ruby tutorial is complete without mentioning Ruby on Rails (often simply called Rails). Created by David Heinemeier Hansson in 2004, Rails is a full-stack web application framework built with Ruby.
Rails follows the “Convention over Configuration” philosophy, which minimizes setup and allows developers to focus on what really matters—building features. This makes Rails one of the fastest ways to develop web applications from scratch.
Example Rails applications include GitHub, Shopify, and Basecamp—proof of Ruby’s scalability and real-world impact.
Why Ruby is Still Relevant Today
You might ask: Why learn Ruby in 2025 when there are so many other languages out there?
Here’s why Ruby still holds strong:
-
Readability: Ruby code is close to natural language, making it accessible and self-documenting.
-
Productivity: Ruby and Rails allow you to build applications quickly, ideal for startups and rapid prototyping.
-
Community: Ruby has a vibrant and supportive community that contributes to thousands of open-source gems (libraries).
-
Career Opportunity: Companies like Shopify, GitHub, and Airbnb continue to invest in Ruby-based stacks.
