What is Ruby?

Ruby is a dynamic, open-source programming language that focuses on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Ruby is widely used for web development, scripting, and prototyping due to its powerful features and flexibility.

Key Features

Dynamic Typing: Ruby supports dynamic typing, allowing variables to hold values of any type without explicit declaration.
Object-Oriented: Everything in Ruby is an object, making it easy to work with classes and methods.
Metaprogramming: Ruby allows developers to write code that manipulates other code, providing great flexibility and power.
Gems: RubyGems is a package manager that makes it easy to install and manage libraries and dependencies.
Web Frameworks: Ruby on Rails, a full-stack web framework, is one of the most popular frameworks built on Ruby, facilitating rapid development.

How to Use Ruby

Installation: Download and install Ruby from the official website or use a package manager like Homebrew on macOS.
Set Up Your Environment: Install a code editor like Visual Studio Code or Sublime Text.
Write Your First Script: Create a new file with a .rb extension and write basic Ruby code. For example:
```
puts "Hello, Ruby!"
```
Run Your Script: Open a terminal, navigate to the directory containing your script, and run it using the command:
```
ruby hello.rb
```
Explore Ruby on Rails: If you’re interested in web development, set up a Rails project by running:
```
rails new myapp
```
