Up until now, I've been using a minimal of JS to develop small single page apps to manage my Java web apps. Things have changed and now, I'm expected to become a "Full Stack Developer" concentrating on the Front end of my Apps.This is where this book (and ALL the others in this series) excel. Those of us that learned "just enough JavaScript" to get by can eat this stuff up.In this book and the entire series, Kyle presents the good, bad and fugly of JavaScript. He tells you how to implement best practices and how to get around and even embrace some of the ugly parts of JavaScript. He tells you WHY some of the "features (not bugs)" were implemented and HOW the JS "compiler" implements the features of JS. This is EXTREMELY helpful in understanding the language (I wish there were Java books like this.)These are not beginner books, but I would say that EVERY JavaScript Developer should read and have on their Kindle or Bookshelf. It should be REQUIRED reading for those who want to become JS experts. And I LOVE Kyle's style of writing. It hooks you and keeps you interested.Thank you Kyle Simpson for such great books. ### ⭐⭐⭐⭐⭐ You really don't know Javascript... Finally a book series that covers the language like no other. Start the series @ second book *by D***D on July 13, 2015* This is on of a series of books on JavaScript. Do yourself a favor and buy he series. It's absolutely the best information I have read on the js language. This is the third book in the series. The first book seems to be for complete newbies, but the rest of the series covers language concepts, how the engine processes the code, and it leads you to the promise land of understanding how to use the language optimally, and shines a light on how many have gone to great length to use the language like in a object oriented fashion, and failed.I walk away with a clear understanding of how I want to use javascript from now on. ### ⭐⭐⭐⭐⭐ Tour de force *by A***S on March 15, 2015* Nick Zakas's "High Performance JavaScript" has always been my favorite JS book for senior devs. I can honestly say this piece surpasses that. It's probably the most dense 177 pages I've ever seen. The table of contents accessible from Amazon will enumerate the topics discussed; for the purpose of this review let it suffice that each area is ripped apart to reveal details that virtually any senior developer will be unaware of, and likely be surprised by. The section on loose equality alone is something I anticipate referencing in the future. Very well done. ## Frequently Bought Together - You Don't Know JS: Types & Grammar - You Don't Know JS: Async & Performance - You Don't Know JS: this & Object Prototypes --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/23373291-you-dont-know-js-types-and-grammar](https://www.desertcart.tn/products/23373291-you-dont-know-js-types-and-grammar) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-04-24*
