Wtf does this do

This repository is a companion code project for a YouTube tutorial series about using FlatLists in React Native apps. FlatLists are a built-in tool for displaying scrolling lists of items on mobile screens, like a feed of posts or a list of contacts. If you are learning to build mobile apps and want to understand how to render long lists efficiently, this project shows you how to do it. The project is organized so that different stages of the tutorial are split across separate branches. In version control, a branch is like a separate timeline of the codebase. By switching from one branch to the next, you can see exactly how the code evolved and what changed at each step of the video series. This makes it easy to follow along with the lessons and compare your own work with the finished examples. The target audience is beginner to intermediate mobile app developers who are learning React Native, or anyone following along with the associated video playlist. A product manager or founder learning the basics of mobile development might also find it useful for understanding how common UI patterns like scrolling lists are implemented under the hood. Beyond the connection to the video series, the README does not go into detail about specific features, advanced techniques, or performance tradeoffs. It exists primarily as a reference point for the tutorial rather than as a standalone library or tool you would plug into your own project. You would visit this repo to read the code and learn, not to install it as a dependency.
