Advanced Javascript with Douglas Crockford

I’ve been slowly making my way through Douglas Crockford’s talk on Advanced Javascript and even at only about 3/4 of the way through the first installment I’ve learned plenty!

The presentation is in three parts and so far he’s covered a bunch of standard programming patterns and elements (singletons, private members, namespaces, constructors, etc…) implemented using Javascript as well as a detailed account of how the language is implemented. Rather than having to work out by trial and error what variables and functions are available where, or how to implement private functions or a singleton, he’s given you the first principles so you can work it out for yourself and a bunch of useful examples.

I highly recommend watching it. I find the more languages I learn the better I get at doing things across the board.
