This is a top-notch, well executed JavaScript course on Udemy by Jonas Schmedtmann. It is about 70 hours long course which teaches you JavaScript from an absolute beginner's perspective upto an expert level programmer.
In this repository, I will upload files from Jonas' JavaScript repository as I have done the same work, and in future I will create another repository on JavaScript to represent my work, and the reason I have shared everything on this README file so that everyone understands that this is kind of a bootcamp repository and not my personal work.
