Thanks for the hints, really appreciate!
A tutorial that I really like is this one: http://xahlee.info/js/js.html. It's really concise and straight to the point.
I also did an interactive test based on it: https://jsquest.herokuapp.com/
Nice resources! I use Codewars for these kind of exercises. It's social oriented and the challanges are organizes in categories, based on difficulty. Also, the diversity of supported languages are great - JavaScript, CofeeScript, TypeScript, PHP, Haskell, Elexir, PHP, Java, C++, C#, Python, etc.
