Hello WASM

Initial Setup

rustup target add wasm32-unknown-unknown --toolchain nightly
cargo +nightly install wasm-bindgen-cli
cargo +nightly new hellowasm --lib

Update cargo.toml

Development

Build our project

cargo +nightly build --target wasm32-unknown-unknown
wasm-bindgen target/wasm32-unknown-unknown/debug/hellowasm.wasm --out-dir .

Now, in our plain javascript file index.js, we can import our generated hellowasm.js and use the greet function.
