    Super QuickStart - Web JavaScript

    Here's a super basic version of how to use the High Fidelity Spatial Audio Client Library in the Web JavaScript context:

    <script src="https://hifi-spatial-audio-api.s3-us-west-2.amazonaws.com/releases/latest/HighFidelityAudio-latest.js"></script>
        // Set up the initial data for our user.
        // They'll be standing at the origin, facing "forward".
        let initialHiFiAudioAPIData = new HighFidelityAudio.HiFiAudioAPIData({
            position: new HighFidelityAudio.Point3D({ "x": 0, "y": 0, "z": 0 }),
            orientation: new HighFidelityAudio.OrientationQuat3D({ "w": 1, "x": 0, "y": 0, "z": 0 })
        // Set up our `HiFiCommunicator` object, supplying our media stream and initial user data.
        let hifiCommunicator = new HighFidelityAudio.HiFiCommunicator({
            initialHiFiAudioAPIData: initialHiFiAudioAPIData
        // `audioMediaStream` is obtained from a separate `getUserMedia()` call.
        await hifiCommunicator.setInputAudioMediaStream(audioMediaStream);
        // Connect to the High Fidelity Audio Spatial API Server by supplying your own JWT here.
        // Follow this guide to get a JWT: https://www.highfidelity.com/api/guides/misc/getAJWT
        // If you don't need a guide, obtain JWT credentials after signing up for a developer account at https://account.highfidelity.com/dev/account
        const HIFI_AUDIO_JWT = "";
        try {
            await hifiCommunicator.connectToHiFiAudioAPIServer(HIFI_AUDIO_JWT);
        } catch (e) {
            console.error(`Error connecting to High Fidelity:\n${e}`);
