Getting Started with WebAssembly (WASM) with Rust Lang

In this video we create, build and execute some webassembly using Rust. We look at:

how to scaffold your webassembly project in Rust
how to build your webassembly project in Rust (including apple m1)
how to execute your wasm code in node.js
how rust generated wasm compares to hand-coded wasm
reverse engineering your wasm to webassembly text format (wat)

00:00 - intro
01:08 - installing wasm-pack
02:50 - creating a rust library for your wasm module with cargo
03:47 - exploring the scaffolded library in vscode
04:59 - modifying the cargo.toml
07:18 - writing some rust webassembky code in vscode
12:28 - building rustlang wasm with apple m1 silicon
14:13 - exploring the generated wasm
15:59 - reverse engineering wasm to wat
17:49 - optimizing the generated release wasm
21:58 - extending your webassembly in rust
22:29 - building your webassembly for node.js
25:40 - executing your rust generated wasm in nodejs
28:42 - handcoding some webassembly
30:00 - comparing rust generated and handcoded webassembly
31:50 - conclusion
