sharmadivashu860-hue/Mern-Stack-Training ? reverse-engineered prompt

Build me a simple MERN stack training app in JavaScript that I can use to practice the basics end to end.

I want a clean starter project with a frontend, a backend API, and a MongoDB data model, so I can learn how the pieces fit together. Make it easy to add, view, edit, and delete a few simple items, like training notes or practice tasks. Add a basic home page, a list page, and simple forms for creating and updating entries. Keep the design clean and beginner friendly, and include just enough validation and error handling so it feels like a real app.

Set it up so it is easy to run locally, and make sure the code is organized in a way that is easy to understand and extend. If you need to check current docs online while building it, go ahead.
