Learn JavaScript

Javascript, The Core (link) is a great introduction to JavaScript language. 
Good reference material is available from W3C Schools' JS Home (link).
Google's style code (link).

Advanced JavaScript

Since Advanced JavaScript (link) by Douglas Crockford videos are not available, here are some newer ones at
Yahoo's (YUI) JS-related video library (link).

Tips

Creating an object definition, closest to defining a class since the concept of a class does not exist in JS:
myClass.prototype = {
myProperty:”this is a string”,
myMethod:function(parms){
    //method logic here
}
}

var instance = new myClass();
There are other ways, too, but the above method minimizes memory usage as it reuses the object definition for every new object created.

Try out JavaScript online - JSFiddle (link).
