Missing function from tutorial

[bohdaq]

Tutorial does not have urlB64ToUint8Array function declared.

When user will try to make Push Notifications work, they will end up with non existing urlB64ToUint8Array method.

Please include sample into tutorial

Where is urlBase64ToUint8Array mentioned in the tutorial?

By the way the function is defined at https://github.com/GoogleChrome/push-notifications/blob/master/app/scripts/main.js

(Considering this issue is still relevent)urlBase64ToUint8Array is mentioned on this page: https://developers.google.com/web/fundamentals/push-notifications/subscribing-a-user

If needed here's the function

/**
 * urlBase64ToUint8Array
 * 
 * @param {string} base64String a public vavid key
 */
function urlBase64ToUint8Array(base64String) {
    var padding = '='.repeat((4 - base64String.length % 4) % 4);
    var base64 = (base64String + padding)
        .replace(/\-/g, '+')
        .replace(/_/g, '/');

    var rawData = window.atob(base64);
    var outputArray = new Uint8Array(rawData.length);

    for (var i = 0; i < rawData.length; ++i) {
        outputArray[i] = rawData.charCodeAt(i);
    }
    return outputArray;
}

The real question. Why is this not built into browsers?
