just finished a js course on codeacademy. i guess it was only the basics. so can anyone advise me, where to take it further out?
First piece of advice: never listen to an instructor for webbdesign, 9/10 they use and teach old standards and ethics.
Do your work the way they want it, but don't use it in practice unless you can confirm its standard.
AND NEVER EVER FEEL BAD ABOUT USING A FRAMEWORK LIKE JQUERY OR OTHERS.
If you want to make something top notch maybe but for a beginner just fucking around with examples and taking parts of the code from it is a good way to learn imo, even if the resulting code will be a spaghetti mess.
Depends, if no tutorials are available the engine is probably shit and not worth bothering with.
The next step is for you to go on your own path. Depends on what you want to make now, if it's websites, give JQuery a good go. Read one or two quick tutorials and then become friends with the documentation.
Games? Find an engine, and go wild.
