I think the books would take you to a basic knowledge of JS rather than expert level. This is the problem - the amount you need to know to be an effevtive programmer is growing out of control, as we attempt to make more ambitious applications than 10 years ago, for a decreasing (in real terms, unless you are in SV) salary. That means more weekends studying (working for free) to keep your place in this industry.
