100 days to learn JavaScript

The best way to learn something is the hard one... They say.

I'm a medical student, my schedule is just not easy and all my future projets need code(Machine Learning, Website etc)

I want to know how to create from scratch a full fonctionnal Facebook-like website, how do I get there ? Already have the books, the courses and the platform (Pluralsight)

It's been 6 months that I started. First with Python and Django, HTML, CSS after and now JavaScript. I already know some basics but I still don't know how to really code in JavaScript.

From this day, i will be posting my long 100 days journey to learn, master and understand at least the most basic JavaScript...
