Expand "Using WebAssembly" chapter

[GJZwiers]

I'd like to contribute to this chapter but I have some questions:

• What should the scope of the chapter be? That is, should it only cover how to use wasm modules in Deno
  or how to write wasm modules as well? I'm asking because there are already many good resources for the latter on for example MDN and the Rust docs. I think a lot of other content in the chapter would depend on this choice. For example, I could write a page that shows how to write some Rust, use wasm-bindgen to make type bindings and create a module with wasm-pack that can be run in Deno, although most of that page would be similar to what's on MDN.

• On the same note as the first question. should there be a page on optimizing wasm for speed and/or size or should the chapter just link to existing guides on the web for that?

• Should there be a page with a list of helpful resources, maybe with links to for example the web-sys Rust crate, wasm-bindgen docs, and so on?

I'm curious to hear what you think :) Personally, I'd like having some pages that are tailored to Deno + WebAssembly as a lot of tutorials on the web assume Node/npm/Webpack or something along those lines.

It should cover how to use WASM modules in Deno. We don't want to repeat (and later maintain) general guides how to write WASM, instead we should link do MDN and other high quality resources on the topic.

It should link to existing guides.

Sure, such list would be helpful.

Having Deno + WebAssembly tutorials would be great, to fill the gap.
