### AI overview

A tutorial that examines how Kotlin sequences process collection elements and explains their relationship to iterables and iterators. It also demonstrates how to create a custom sequence class and use it in an operation chain.

### Source excerpt

Sequences are a fantastic way to process collections of data in a way that can perform better than the standard collection operations, as we saw in the previous article, Kotlin Sequences: An Illustrated Guide. Today, we're going even deeper! We're going to look under the hood - inside Kotlin sequences - in order to understand how they work like never before! In fact, by the end of this article, we'll even create our very own Sequence class and plug it into an operation chain!
