Ruby &: - Ruby

Ruby is a dynamic, open-source programming language with a focus on simplicity, productivity, and flexibility. It allows developers to write clean and concise code using a syntax that is easy to read and understand.

Features

• Dynamic typing - variables don't need to be declared ahead of time
• Interpreted - code is executed line-by-line instead of being compiled
• Object-oriented - everything is an object, including strings, numbers, and even methods
• Garbage collected - automatically deallocates memory that is no longer being used
• High-level - provides abstractions that make complex programming tasks easier
• Easy to learn - Ruby's syntax is similar to natural language, making it easy to read and write

Example Code

# Define a class
class Person
  attr_accessor :name, :age

  def initialize(name, age)
    @name = name
    @age = age
  end

  def say_hello
    puts "Hello, my name is #{@name} and I am #{@age} years old."
  end
end

# Create a new instance of the class
person = Person.new("Jane Smith", 25)

# Call the say_hello method
person.say_hello
