Reading high quality code helps a ton. See how great programmers write code in the languages they're experts in. You can bet any Javascript written by John Resig is going to be high quality. Learn why he writes code the way he does.

There are style and "best practices" guides for many languages. Python has PEP-8. Perl has the "Perl Best Practices" and "Modern Perl" books. Javascript has "Javascript: The Good Parts". Go has "Effective Go".

John Resig created jQuery. Language/framework creators are usually a good start. Any core contributor to jQuery or Rails is probably a competent Javascript or Ruby programmer.
