A complete JavaScript learning repository from Basics to Advanced. Learning how JavaScript works behind the scenes and building strong core fundamentals.
This repository contains my complete learning journey of JavaScript –
from beginner concepts to advanced topics, including internal working of JavaScript.
I am learning from the "Chai Aur JavaScript" playlist by Hitesh Choudhary
and documenting everything I learn through code examples and detailed notes.
