 Like virtually every human task ever carried out, _Practical Modern JavaScript_ was made possible only by building upon the work of others. I want to thank Nan Barber, my editor at O'Reilly, for her fantastic support along the ride of writing this book. Ally MacDonald, another editor at O'Reilly, helped me out in the early days of the project and is the foremost reason why Modular JavaScript became a book series, as she helped me conjure up a modular approach to teaching JavaScript.
 
-This book had a phenomenal ensemble of technical reviewers. Many of these folks are on TC39, the technical committee devoted to pushing JavaScript forward, and it's deeply humbling that they gave up some of their time to help future-proof this book. As always, Mathias Bynens (ex-Opera) proved instrumental to proofing everything in the book with regards to Unicode standards and held my work to a high degree of consistency in terms of code snippets. Kent C. Dodds (TC39, PayPal) ingeniously offered video reviews where he identified weak spots and helped improve the book. Jordan Harband (TC39, Airbnb) came through with deep technical commentary about many of the JavaScript features discussed in the book, and along with Alex Russell (TC39, Google) helped me iron out the history of JavaScript and its standards body for the first chapter. Ingvar Stepanyan (Cloudflare) was also a sharp eye in identifying code issues and pinpointed mistakes around low-level aspects of the specification. Brian Terlson (TC39 editor, Microsoft) also helped out with timelines and details around TC39. Rod Vagg (Node.js) provided insight that lead to better code examples and more consistent code style throughout the book.

 Brendan Eich (TC39, Brave CEO) provided a trove of insight into the early days of JavaScript and TC39, which proved essential to the development of the first chapter. And naturally, if not for him, you wouldn't be holding this book in your hands.
