FeralSatyam/Sunway_MERN_T1 ? reverse-engineered prompt

Build me a small JavaScript practice project that shows off the basics in a clean, easy to browse way.

I want separate example sections for variables, strings, arrays, functions, objects, and methods, plus a simple backend folder for a basic Node style demo or API starter. Make it feel like a learning playground where I can open each file and quickly understand what it does from the code and comments.

Please keep it simple and organized, with a few useful examples in each area, not just empty placeholders. If you need to check current best practices or syntax details, look them up online. Make sure the project runs without errors and is easy to extend with more lessons later.
