sachinkumar-git/MERN-Development-Track ? reverse-engineered prompt

Build me a clean, well organized MERN learning track repo that walks through the basics of web development all the way to full stack apps.

I want separate sections for HTML, CSS, JavaScript, React, Tailwind, Node, Express, REST APIs, SQL, MongoDB, middleware, error handling, and database relationships. Each section should have practical examples, simple exercises, and small code samples that actually teach the concept instead of just notes. Keep the structure easy to follow so I can open any folder and understand what it is for right away.

Make it feel like a real progression from frontend fundamentals to backend and database work, with a few small projects or mini demos along the way. Also polish the README so it explains the learning path clearly, shows what each module covers, and makes it easy to get started. If you need to check current docs for anything, feel free to look them up online.
