wtf is redux-tutorial?

Redux is a tool that helps manage how data flows through a web application. Think of it like a filing system for your app's information, instead of different parts of your code randomly changing data whenever they feel like it, Redux enforces a single, organized process. Someone wants to change something? They submit a request (called an "action"), that request goes through a review process (called a "reducer"), and only then does the actual change happen. This makes it much easier to track what changed, when it changed, and why. This tutorial teaches you how Redux works by walking you through numbered JavaScript files, starting from the basics and building up to more complex ideas. Each file focuses on one concept, like how to create an action, how reducers work, or how different pieces connect together. You can read through them in order, and each example is actually runnable code that you can execute on your computer to see Redux in action. This hands-on approach means you're not just reading theory, you're seeing real, working examples that you can experiment with and modify. The tutorial is geared toward people who already know some JavaScript and want to understand how Redux fits into building web apps. It's especially useful if you're working with React, a popular library for building user interfaces, since Redux and React work well together. Rather than trying to cover every advanced feature, this tutorial gives you a solid foundation so you can move on to the official Redux documentation once you understand the core ideas. The README notes that this targets older versions of Redux, so if you're starting a brand new project today, you'd want to check the current Redux documentation for any updates. But the fundamental concepts of how Redux manages data flow remain the same, making this a good stepping stone for understanding state management in general.
