What are advanced iterators in Ruby on Rails?

Advanced iterators in Ruby on Rails are methods that allow you to traverse collections in more complex ways than basic iterators.

Can you give me an example of an advanced iterator?

Sure! One example is the each_with_index method, which iterates over a collection while keeping track of the index.

How does each_with_index work?

each_with_index yields each element along with its index, allowing you to access both the value and its position in the collection.

Are there any other useful advanced iterators?

Yes, methods like map, select, and inject are also considered advanced iterators that provide powerful ways to manipulate collections.
