Can't alert javascript variable

Question

I'm trying to print the contents of my digest variable but not having any luck. The below is the code I have. I've read a few tutorials and can't see why it wouldn't work.

  // Store Credentials
  var userName = "username";
  var sharedSecret = "secret";

  // Build Header
    var date = new Date();
    var nonce = md5(Math.random());
    var nonce_ts = date.toISOString().replace(/(\.\d\d\dZ)/ ,'Z');
    var digest = (new Buffer(sha1(nonce + nonce_ts + sharedSecret)).toString('base64'));

  alert(digest);

It was taken from nodeJS and I am trying to make it javascript.

This looks like NodeJS, NodeJS doesn't have a native alert function, try console.log — Luca Kiebel

@Cerbrus Ok I think that is the problem. I took from nodeJS to try and make JS. Do I need to recreate this function in JS? — Jimmy

node (like a browser) has a JavaScript engine to run JS code. alert, md5, Buffer are not part of the JavaScript language specification, but are part of an API provided directly by the environment or by a foreign library. — t.niese

Then you need to make sure md5, sha1 and Buffer are ported over to your JavaScript environment. These aren't normally available in a browser.

The reason you're not getting an alert window, is because the code is crashing on those function. You can easily see that by opening your browser's developer console (Usually F12)

(I've found this library for Buffer, and another one for md5 and sha1)
