I wasn't sure what to expect from this book as it's more than just an introduction to WebGPU - it also gives you a taste of everything from ray-tracing to fractas! But after reading it for a few weeks, I have to say, it's a real gem. I got the hardback version as it feels nicer and has more room in the margins for notes - I find it spends more time on my desk than it does on the shelf like other books.
