Unfortunately Richard Stanley hasn't updated the blog in more than 6 months, but in any case. If you want to sharpen your JS skills I'd highly recommend the site.
Javascript is honestly a weird language if you're coming from the typical imperative languages (C, Java, Python, etc.), it's also not really functional enough to be in the spirit of Lisp, and it's doesn't have the type system to be familiar to Haskell or Scala devs. It's really a descendant of the Smalltalk/Self lineage, but with some major diversions. I always thought it was a shit language cobbled together with no consistent philosophy. Reading that book proved me wrong. Javascript does in fact have a soul and Reg Braithwaite totally changed how I view the language with Javascript Allongé.
We are thinking about adding a section on the most used libraries or frameworks, such as Backbone, Angular and Ember, but we will focus on the core JavaScript essentials until we feel it's good enough.

edit I'm laughing at the irony, not the claim of copyright infringment.

Nonetheless, thanks for putting this together!
I think there would be a great demand for people specialized in memory leak / performance tuning etc
