I tried really hard to deliver pretty advanced content in such a way that it's simple and easy to understand, while trying to avoid talking down to the readers as if they were children. Looks like it worked 😊 To quote a reviewer: "Like a talk with a colleague in simple words and on topic".

Kicked off the "Testimonials" section for the "Web Performance Fundamentals" book (www.getwebperf.com) with very lovely feedback from the early readers. "Detailed", "on topic", and "simple" are the general themes of the feedback so far :)

While you're reading, I'm off to write a sequel: what's the difference between Context, Redux, Zustand, and how to choose the best state management these days. In the meantime, the **WEBPERF30** discount on both of my books still works and will be till the end of the month!

It's absolutely not for beginners, though; prior experience is pretty much mandatory.

Nadia Makarevich @adevnadia.bsky.social · 12/06/2025

Core target audience: middle to senior React developers who want to deepen their knowledge and tap into web performance. Secondary target audience: any frontend developer interested in web performance who doesn't mind dealing with React on occasion.

100

Nadia Makarevich @adevnadia.bsky.social · 12/06/2025

Nevertheless, all examples are written in React, some of the aspects are deeply intertwined with React's specifics (like SSR), and some of them are purely React specifics, like React Server Components. So, keeping "React" somewhere in the subtitle seems fair.

100

Nadia Makarevich @adevnadia.bsky.social · 12/06/2025

The rationale👇🏼 The book is all about _web performance_: how to investigate, measure, and understand it. 70% of the book has nothing to do with React itself: it's about fundamental web knowledge applicable to any web app, SPA or not. So I'd like to avoid "React" in the title.

Nadia Makarevich @adevnadia.bsky.social · 12/06/2025

This is happening and pretty soon! The new book is coming, final polish in progress. In the meantime, which title do you like best? "Beyond Re-renders Web Performance Fundamentals for React Developers" "Web Performance Fundamentals Profile & Optimize React Web Apps" 🧵👇🏼
