Filled gaps I didn't know I had
Been writing JS for 3 years and thought I knew it well. Turns out I had some fundamental misunderstandings about scope and closures that this cleared up immediately.

Challenging in a good way
Not an easy read, but that's the whole point of an advanced book. The sections on memory leaks and garbage collection were eye-opening. Would love a follow-up on Node.js internals.

JS mastery unlocked
Prototypal inheritance, WeakMaps, Proxies, advanced async patterns -- this goes deep where most resources stay shallow. The performance optimization chapter is packed with techniques I immediately applied at work.
