I wrote a book.

Book cover

This book is a deep dive on how React works on the inside that can help you understand its internal mechanisms more deeply and unlock greater levels of fluency.

It was curated by me, published by O'Reilly, and thoroughly reviewed a number of peers including the React core, experts, friends, and more.

    I got dropped into web dev via corporate mandate 6 yrs ago, so I love that Fluent React begins by outlining the ecosystem of the time β€” something I was largely disconnected from. This context has helped me appreciate everything I’ve learned so much more. @TejasKumar_ πŸ™

    V excited for this. As someone who has used React for years but never as my only focus, it will be interesting to see how this deepens knowledge for me I'm a huge fan of @TejasKumar_ as a person and enjoy his teaching style so I expect to feel more of that same vibe in this book

    Fluent React by @TejasKumar_ is an amazing book. Learning React by reading a book is a completely new experience.
