   I've been working in the performance industry (focusing on front-end performance and UX) for 15 years. Some resources you might find helpful:

   • Steve Souders' books 'High Performance Web Sites' & 'Even Faster Web Sites' – https://stevesouders.com/ – Steve literally wrote the book(s) on performance and is widely considered the godfather of the industry.

   • WPO stats – https://wpostats.com/ – Case studies and experiments demonstrating the impact of performance optimization on UX and business metrics

   • performance.now() talks – https://www.youtube.com/c/WebConferencesAmsterdam/videos – PerfNow is the only annual global conference dedicated to performance. You can watch past talks on their YouTube channel.

   • Intro to Web Performance – https://support.speedcurve.com/docs/psychology-of-web-perfor... – This is a collection of introductory articles covering topics like the psychology of sit speed to Core Web Vitals to how to create a performance culture in your organization.

   A bit older, but both worth a read, and most of this is still relevant today...

   I find the Steve Souders' books [1] "High Performance Web Sites" and "Even Faster Web Sites" methods are still fairly practical, not all of it applicable to JS directly, but still.

   In the end, you'll need to test your changes in the most common browsers that affect you, because each browser's JS engine can vary a lot. The lookup cost you mention can be deceptively expensive, especially if you have anything resembling a deeper inheritance tree, or worse, proxies, getters/setters etc.

   In the end, a lot of it doesn't matter, until it does.

   Great start! Here are a few other books I've read recently and marked the crap out of because there is so much good information in them.

     - JavaScript Patterns by Stoyan Stefanov
     - High Performance JavaScript by Nicholas C. Zakas
     - High Performance Web Sites by Steve Souders
     - Even Faster Web Sites by Steve Souders
   

   Here are a few I haven't read yet but are on my to read list.

     - Object-Oriented JavaScript by Stoyan Stefanov
     - Pro JavaScript Design Patterns by Dustin Diaz, Ross Harmes

   Get the two Souders (creator of YSlow, now works on web performance at Google) books, which are amazing. I'm not affiliated with Amazon.com, O'Reilly or Yahoo!; just like Patrick says, these guys know their shit:

   High Performance Web Sites (O'Reilly, Sept. 2007): http://www.amazon.com/High-Performance-Web-Sites-Essential/d...

   Even Faster Web Sites (O'Reilly, June 2009): http://www.amazon.com/Even-Faster-Web-Sites-Performance/dp/0...

   Half of King's 'Website Optimization: Speed, Search Engine & Conversion Rate Secrets' (O'Reilly, July 2008) is devoted to performance, so it's also worth a look: http://www.amazon.com/Website-Optimization-Search-Conversion...

   One can write a book about literally anything. But besides that, it already "required" a book – at least two of them in fact, both published before Google even announced SPDY: "High Performance Web Sites" [1] in 2007 and its sequel "Even Faster Web Sites" [2] in 2009, both by Steve Souders.

   What are they about? Essentially, optimizing your HTTP responses for the ways in which actual web browsers make HTTP requests. Any web performance analysis tool worth using (like YSlow and PageSpeed – both of which Steve Souders was involved in btw) recommended the practices outlined in those books.

   So, no. I don't think a new book with updated practices says anything about the protocol. The optimization tips from this book will simply become widespread common knowledge the same way they did in the past.
