🚀 Daily JS practice — variables, arrays, functions, DOM & more. Day 8 streak!! 💪
"Future Muskan is depending on what I do tonight."
A personal JavaScript practice repository documenting my journey from basics to full-stack MERN development — one day at a time. 💪
This is my daily JavaScript practice log. Every file here represents real hands-on practice — no copy-paste, no shortcuts. Just genuine learning through building and breaking things.
Started: April 2026 Goal: Land a web developer job 🎯 Stack: JavaScript → React → Node.js → MongoDB
Beginner JavaScript learners who want structured daily practice with real examples.

I maintain a personal cheatsheet.js file with everything I learn — written in my own words, not copied. Check it out to see how I think through concepts!!
