I wrote a book about the inner workings of the V8 engine. It's around 50 pages, and every page contains valuable information, there’s no bs or AI slop. I explain how your JavaScript engine turns human-readable code into bytecode and eventually into 1s and 0s, and how JavaScript manages its single-threaded behavior without breaking.

I wrote everything in a way that anyone can understand. It’s the kind of book I wish I had when I was trying to learn how JavaScript really works and executes code.

It’s free for 4 days. I’m not asking you to read the whole book, but I would really love to get your feedback.

(I’ll delete this post after 3 days since after that it might look like I’m promoting a paid product.)

I would have prefer a [java|ecma]script engine I can build with a simple C compiler like quickjs, mujs, duktap, etc.
