atob === Uses `Buffer` to emulate the exact functionality of the browser's atob. Note: Unicode may be handled incorrectly (like the browser). It turns base64-encoded **a**scii data back **to** **b**inary. (function () { "use strict"; var atob = require('atob') , b64 = "SGVsbG8gV29ybGQ=" , bin = atob(b64) ; console.log(bin); // "Hello World" }()); Copyright and license === Code and documentation copyright 2012-2014 AJ ONeal Tech, LLC.
