Hello, I’m quite new to Zig, recently I’ve been playing with using it for WASM and had some (mis)adventures, so I wrote up all the things I learned:

> **[Using Zig with WebAssembly](https://blog.mjgrzymek.com/blog/zigwasm)**
>
> How to send numbers, strings, and arbitrary objects to Zig WASM

If anyone knows

1. What is `__stack_pointer`? (I also asked this on [SO](https://stackoverflow.com/questions/78093023/what-is-stack-pointer-in-zig-wasm))
2. What’s happening to pages 15 and 16 in section Memory?

it would be a help. Thanks!
