Import JavaScript things into Rust and export Rust things to JavaScript.

extern crate wasm_bindgen;
use wasm_bindgen::prelude::*;

// Import the `window.alert` function from the Web.
extern {
    fn alert(s: &str);

// Export a `greet` function from Rust to JavaScript, that alerts a
// hello message.
pub fn greet(name: &str) {
    alert(&format!("Hello, {}!", name));

Use exported Rust things from JavaScript with ECMAScript modules!

import { greet } from "./hello_world";
