### **Key Features of Ruby**
1. **Object-Oriented**: Everything in Ruby is an object, including primitive data types.
2. **Dynamic Typing**: No need to declare variable types; types are resolved at runtime.
3. **Readable Syntax**: Designed to be natural to read and write, resembling English.
4. **Metaprogramming**: Ruby allows writing code that modifies itself at runtime.
5. **Garbage Collection**: Automatic memory management.
6. **Mixins (Modules)**: Supports multiple inheritance via modules.
7. **Blocks & Lambdas**: First-class support for functional programming concepts.
8. **Ruby on Rails**: A highly popular web framework built with Ruby.
### **Example Code**
```ruby
# Hello World
puts "Hello, World!"
# Define a method
def greet(name)
puts "Hello, #{name}!"
end
greet("Ruby") #=> "Hello, Ruby!"
# Class example
class Person
attr_accessor :name
def initialize(name)
@name = name
end
def introduce
puts "My name is #{@name}."
end
end
person = Person.new("Alice")
person.introduce #=> "My name is Alice."
```
### **Ruby on Rails (Rails)**
- A full-stack web framework built on Ruby.
- Follows **MVC (Model-View-Controller)** architecture.
- Convention over Configuration (CoC) and Don’t Repeat Yourself (DRY) principles.
- Used by companies like GitHub, Shopify, Airbnb, and Basecamp.
### **Pros of Ruby**
? Easy to learn and write
? Strong community support
? Great for rapid development
? Rich ecosystem (gems for everything)
? Elegant and expressive syntax
### **Cons of Ruby**
? Slower than compiled languages (like Go or Rust)
? Not ideal for high-performance computing
? Memory-heavy compared to some alternatives
### **Use Cases**
- **Web Development** (Ruby on Rails, Sinatra)
- **Scripting & Automation**
- DevOps Tools** (Chef, Puppet)
- Prototyping & Startups
