# Base64.js
≈ 500 byte* polyfill for browsers which don't provide [`window.btoa`][1] and
[`window.atob`][2].
Although the script does no harm in browsers which do provide these functions,
a conditional script loader such as [yepnope][3] can prevent unnecessary HTTP
requests.
```javascript
yepnope({
test: window.btoa && window.atob,
nope: 'base64.js',
callback: function () {
// `btoa` and `atob` are now safe to use
}
})
```
Base64.js stems from a [gist][4] by [yahiko][5].
