What are Ruby iterators and how do they work?

Ruby iterators are methods that allow you to traverse through collections like arrays and hashes. They enable you to perform operations on each element without explicitly using loops.

Can you give me an example of a simple iterator in Ruby?

Sure! A common iterator is the each method. For example, array.each { |element| puts element } will print each element of the array.

What other iterators are available in Ruby?

Ruby offers several iterators like map, select, reject, and reduce, each serving different purposes for data manipulation.

How do I create my own iterator in Ruby?

You can create your own iterator by defining a method that yields values. For example, def my_iterator; yield 1; yield 2; end allows you to use it like my_iterator { |x| puts x }.
