Base64.js

≈ 500 byte* polyfill for browsers which don't provide window.btoa and window.atob.

Although the script does no harm in browsers which do provide these functions, a conditional script loader such as yepnope can prevent unnecessary HTTP requests.

yepnope({
  test: window.btoa && window.atob,
  nope: 'base64.js',
  callback: function () {
    // `btoa` and `atob` are now safe to use
  }
})

To add via requirejs use something like:

require(["base64"], function(base64) {
    window.atob = base64.atob
    window.btoa = base64.btoa
});

Base64.js stems from a gist by yahiko.
