Overall, a good presentation, but I think the description of prototypes could have been clearer.  The diagram of the prototype chain implied that an object could inherit from multiple prototypes, which is not correct.  Luke didn't different between the inheritance prototype of an object and the creational prototype used by a constructor function when it creates a new object.  Not doing that caused confusion and made the diagram look like there was multiple inheritance going on.

Otherwise, very good.

A very useful, practical presentation.
