JavaScript is such an amazing language!
Born as a simple way to manipulate documents in the browser, over the years it became the most popular programming language in the world, and now runs everywhere.
Here is an attempt to draft a roadmap to learn JavaScript.
Note: I added all those in a handy PDF/ePub, download it now
Beginner’s guides
