Ruby is a dynamic, object-oriented programming language that is known for its simplicity and elegance. It was designed and developed by Yukihiro Matsumoto, who wanted to create a language that emphasized human-readable code and productivity.
Ruby is a fully object-oriented language, which means that everything in Ruby is treated as an object. Objects encapsulate data and behavior, allowing developers to easily organize and manipulate data structures.
Ruby is dynamically typed, which means that variable types are checked at runtime. This allows for more flexibility and faster development, as variables can be assigned without explicitly specifying their type.
Ruby provides dynamic reflection capabilities, allowing developers to access and modify code at runtime. This enables creating powerful metaprogramming techniques, such as defining methods dynamically or modifying existing ones.
One of Ruby's greatest strengths is its syntax, which is designed to be both readable and expressive. The code is often described as having a natural language-like quality, making it easy for beginners to learn and understand.
Ruby has a thriving community and a wide range of libraries and frameworks that make development faster and more efficient. Ruby on Rails, a popular web application framework, is built on top of Ruby and is known for its simplicity and productivity.
To write and execute Ruby code, you will need to install the Ruby interpreter on your machine. Ruby is available for all major operating systems, including Windows, macOS, and Linux.
Once Ruby is installed, you can write Ruby code in a text editor and save it with the .rb extension. To execute the code, open the terminal or command prompt, navigate to the file's directory, and type ruby filename.rb.

puts "Hello, World!"The above code is a simple example that prints "Hello, World!" to the console. Running the file with ruby hello_world.rb will display the greeting.
Ruby is a powerful and elegant programming language that prioritizes simplicity and productivity. It is widely used and supported, with an active community that continuously contributes to its growth and development. Whether you are a beginner or an experienced developer, learning Ruby can be a rewarding journey that expands your programming skills.
