Ruby is a dynamic, reflective, object-oriented programming language known for its simplicity and productivity. Developed in the mid-1990s by Yukihiro Matsumoto, or “Matz,” Ruby was designed with a focus on programmer happiness and productivity. It combines elements from several programming languages, including Perl, Smalltalk, Eiffel, and Lisp, to create a language that is both elegant and powerful.

Ruby Programming Key Point & Feature
- Simplicity: Ruby’s clean syntax emphasizes simplicity and expressiveness, enabling developers to focus on problem-solving rather than complex syntax.
- Object-Oriented: Ruby is fully object-oriented, supporting principles like encapsulation, inheritance, and polymorphism for building modular and reusable code.
- Dynamic Typing: With dynamic typing, variable types are determined at runtime, offering flexibility in coding but requiring careful testing and error handling.
- Metaprogramming: Ruby’s support for metaprogramming allows for dynamic modification and extension of code at runtime, facilitating the creation of domain-specific languages and elegant solutions.
- Rich Standard Library: Ruby boasts a rich standard library covering various tasks such as file I/O, networking, and string manipulation, supplemented by RubyGems for easy management of third-party libraries.
- Rails Framework: Ruby on Rails (Rails) is a powerful web application framework that follows the convention over configuration (CoC) and don’t repeat yourself (DRY) principles, enabling rapid development of scalable and maintainable web applications.
