This book goes in deep on a lot of object-oriented stuff, and other corners of the JS including events, debugging, functions, etc. This seems overall solid, but a) it was last updated 6 years ago and a lot has changed in the JS landscape since then, and b) the OOP stuff takes up a good chunk of it. If you need to work in that kind of paradigm, this may be useful, it feels less than helpful for most modern JS devs.

I got a job as a frontend developer because of this book.

I’m the kind of person who needs a true understanding of something before I can speak confidently about it.

The thorough knowledge that I gained from chapters like closures, event loops, and promises helped me wow interviewers.

I passed all spoken JavaScript interviews ever since I read this book.

One tip is that the book first emphasizes the functional programming side of JavaScript (which helps immensely if you use React and react hooks) but many places interviewed me on object oriented concepts.

Functional is an important JavaScript paradigm so don’t skip it, but I suggest prioritizing some chapters if you’re job searching.
