Why would anyone build with this?

REASON 1

Learn how Redux-style state management works by reading a tiny, readable implementation.

REASON 2

Add simple, predictable state management to a very small project without a full Redux install.

REASON 3

Use as a teaching reference to understand actions and reducers before using real Redux.

REASON 4

Play with the live to-do list demo to see actions and reducers update state in real time.

Wtf does this do

This is a tiny, educational version of Redux, a popular tool for managing app state, built from scratch to show how it actually works under the hood. It's less than 1 kilobyte in size and has zero dependencies, meaning it doesn't rely on any other libraries to run. The main idea is to help developers understand the core concepts behind state management by stripping away the complexity of the real Redux library. The demo includes a simple to-do list app that shows the state management in action. You can add, remove, or check off tasks, and the tool handles keeping track of all those changes in a predictable way. For anyone learning web development, this makes it easy to see how state management actually works without getting lost in production-grade complexity. The core concept is straightforward: instead of having data scattered across different parts of your app, everything lives in one central place called "state." When you want to make a change, you send an action describing what you want to do, and a "reducer" function figures out how to update the state based on that action. This predictable flow makes it easier to track what's happening in your app and debug problems. You'd use this if you're a developer learning how state management works, or if you're building a very small project where a full Redux installation feels like overkill. Because it's so minimal and has no external dependencies, it's also useful as a reference for understanding what's really happening when you use the larger Redux library in a real project. The to-do list demo is live on GitHub Pages, so you can play with it directly without needing to set anything up.
