Methods allow you to encapsulate reusable pieces of code and execute them with different arguments. In this tutorial, we'll explore the fundamentals of Ruby methods, including how to define them, pass arguments, return values, and more.

In Ruby, methods are defined using the def keyword followed by the method name, parameters (if any), and the method body. Here's a simple example.

def hello
  "Hello, World!"
end

hello #=> "Hello, World"
