Javascript book recommendation needed

[David Cantrell]

My god, my Javascript SUCKS.  I've not done any serious Javascript 
programming for ten years and I've forgotten *everything*.  So I need a
book.  Can anyone recommend one, suitable for an experienced programmer 
who just doesn't know this particular language, and which talks about
data structures and the language itself (bonus points for covering
closures) and spends only minimal time talking about web shit?
