taqsiimTQ/NTI-MERN ? reverse-engineered prompt

Build me a simple JavaScript practice repo for a MERN learning track, organized into separate day folders from day1 to day10.

I want each day to feel like a small working lesson, with clear example code and a few basic exercises or starter files so someone can open a folder and understand what it does right away. Keep it beginner friendly, with the later days building on the earlier ones in a natural way.

If it helps, make the project easy to run and easy to extend, and add short notes in the files so I can tell what each day is about. If you need to check current setup details online, go ahead and do that.
