Ruby Programming Language Tutorial
Hello and welcome to this tutorial on Ruby, a dynamic and expressive programming language that is easy to learn and fun to use. Ruby is an object-oriented language, which means that everything in Ruby is an object. Objects have methods, which are actions that the object can perform, and attributes, which are data that the object stores. For example, a string object has methods like upcase and reverse, and attributes like length and encoding. You can create your own objects by defining classes, which are blueprints for objects.

FAQ’s of Ruby Programming Language
What is Ruby, and why should I learn it?
Ruby is a dynamic, object-oriented programming language known for its simplicity and developer-friendly syntax. Learning Ruby can be beneficial because it’s widely used in web development (with Ruby on Rails), scripting, automation, and more. Its elegant code design and strong community support make it an attractive choice for many developers.
What is Ruby on Rails, and how is it related to Ruby?
Ruby on Rails, often referred to as Rails, is a web application framework built using the Ruby language. It simplifies web development by providing a set of conventions, tools, and libraries for building web applications. Ruby on Rails is one of the most popular frameworks for web development and is closely associated with Ruby due to its primary use of the language.
Is Ruby a statically typed or dynamically typed language?
Ruby is a dynamically typed language. This means you don’t need to declare the data type of a variable explicitly; the type is determined at runtime. While this offers flexibility, it can also lead to runtime errors if not used carefully.
What is the RubyGems package manager?
RubyGems is a package manager for Ruby that allows developers to easily distribute, install, and manage libraries and dependencies (called “gems”) for Ruby projects. It simplifies the process of adding external functionality to your Ruby applications by providing a centralized repository of gems.
Are there any notable companies or projects that use Ruby?
Yes, several well-known companies and projects use Ruby for various purposes. Some examples include Airbnb, GitHub, Shopify, and Basecamp. These companies have utilized Ruby, particularly with the Ruby on Rails framework, to build and maintain their web applications. Additionally, many open-source projects and startups use Ruby for its productivity and expressiveness.
