Answer 3

I learned JavaScript by doing...
first some small projects, later bigger ones. On the very first day I started I refered to selfhtml! https://wiki.selfhtml.org/wiki/JavaScript
I started doing the HTML and then made the magic with JavaScript. Everytime i stucked selfhtml helped me out with cool examples.
If you are familar with JavaScript have a look with Ajax you can not imagine how powerfull it can be.
