The very core of the content here is good, actionable advice and matches up with my experience.
But there's a lot of repetition, fluff and content that's may or may not be relevant to you.
Coming from a native Android & iOS stack viewpoint: there's quite a lot of web-specific stuff here that, while interesting to know about, isn't all that useful.
There's also a surprising amount of time spent on specific tools, which seems like it will get outdated quick. Which, hey, makes it quickly actionable if you read it right now, but in a few years? Likely will need a new edition.
A bit painful to say this but you'd be better served reading the author's blog posts and the discussion on Book Overflow (which is where I heard of it first)
I can't hate on the man too much, gotta earn a living! This feels like a case of expanding on a few great blog posts and adding a whole bunch of filler.
A generous three stars.
