+ - Run `build.sh` or `build.ps1`, then then start a dev server that supports WASM.
 For example, with [Python](https://www.python.org/downloads/) installed, run `python server.py`.
 (Linux users may need to run `python3 server.py`.)

    // The `--no-modules`-generated JS from `wasm-bindgen` attempts to use
    // `WebAssembly.instantiateStreaming` to instantiate the wasm module,
    // but this doesn't work with `file://` urls. This example is frequently
    // viewed by simply opening `index.html` in a browser (with a `file://`
    // url), so it would fail if we were to call this function!
    //
    // Work around this for now by deleting the function to ensure that the
    // `no_modules.js` script doesn't have access to it. You won't need this
    // hack when deploying over HTTP.
