What is the difference between enumerators and iterators in Ruby?

In Ruby, iterators are methods that allow you to traverse a collection, like each, while enumerators are objects that encapsulate the iteration logic.

Can you give me an example of an iterator?

Sure! The each method is a common iterator. For example, array.each { |item| puts item } prints each item in the array.

And how do enumerators work?

Enumerators can be created using to_enum or enum_for. They allow you to control the iteration process more flexibly.

What are the advantages of using enumerators over iterators?

Enumerators provide more control, allowing you to pause and resume iteration, and can be used with different enumerating methods.
