"Ruby ranges are a way to represent a series of numbers or characters. They can be used for iteration, comparison, and arithmetic operations. There are several ways to define ranges:

1. Using two numbers (inclusive):
(start..end) - Includes the end number
(start...end) - Does not include the end number

2. Using a single number:
n..n - Represents a single value

3. Using three dots for an infinite range:
start..Float::INFINITY
start...Float::INFINITY

For example:

(1..5).each { |number| puts number }

This will output '1 2 3 4 5'."

Tell me the role of modules and mixins in ruby?
