I've been learning Javascript on Codeacademy, but the site is so buggy and broken that the fact it's free of charge and breaks lessons down into small pieces isn't helping me. All I experience is frustration with the broken Run button and command parser, as well as the lazy and inefficient staff who run the site. So I need to start fresh learning the most up to date Javascript. Please recommend a resource.
Also, I'm gathering that I should learn XML and CSS before I learn Javascript, so, if I should start there, then maybe you can refer me to a good beginner resource on them.
Thanks. :)
