wtf is react-tutorial-hot?

This is an outdated example project that demonstrates React development with a live-editing feature. The repo takes the official React tutorial's comment box example and adds the ability to see your code changes instantly in the browser without refreshing the page, a workflow feature called "hot reloading." Normally, when you're building a web app and you change some code, you have to manually refresh your browser to see the result. This project lets you skip that step. You edit the code files, and the changes appear on screen immediately. It's a small convenience, but it makes the development experience smoother, especially when you're learning and experimenting. The project itself is simple: it's a comment box interface built in React, which you can run locally on your machine. After installing dependencies and starting the server with a couple of commands, you visit it in your browser and can start editing the component files to see live updates. However, the README makes it clear this specific repository is no longer maintained. The author (Dan Abramov, a core React contributor) has moved on to other tools and starter kits that do the same thing in better ways. If you're starting a new React project today, you'd want to look at one of the more modern alternatives mentioned in the README rather than clone this one. This repo is mainly useful as a historical reference or for understanding how live reloading was achieved in early React tooling.
