Awesome! You're exactly the kind of person we were thinking of when we wrote the book…experienced programmers who are interested in understanding things at a lower level. Let us know how it goes! You can find us in the book Discord, or

Edit: changed slightly to provide a more useful answer. No, it doesn't — not this version of the book at least. We only cover WebAssembly 1.0. That said, as my co-author says below, there's really not much to tail calls. Once yo

Thank you! I would 100% agree that the spec is quite readable. At the top of our Minimum Viable Compiler chapter, we say: > The binary module format is defined in the WebAssembly Core Specification. You’ll notice that we back up many o

Yes, it can all be found here: https://github.com/wasmgroundup/code Over the course of the book, we also build up a small library for creating Wasm modules and emitting bytecode; that's available as an NPM package

It's explained in the post: > Then, my plan was to construct a ProseMirror transaction that would turn the old tree into the new one. To do that, it’s helpful to know which nodes appeared in the old document, but not the new one. So

I think you're skipping over some important distinctions here. In a mark & sweep GC, the mark phase traverses the object graph, visiting only live objects. You need to recursively visit any objects that are not already marked — thi

(OP here) It’s possible, but I doubt it. Perhaps the way I wrote it makes it sound like I was thinking about it as a GC problem from the beginning, but I wasn’t. It wasn’t until I started seeing it as as being like GC that (a) I realized th

I'm not sure I totally understand what you mean by "in-process" here. But you could have some JavaScript that compiles some code in your custom language to WebAssembly and then execute it, and you can use the browser dev tool
