@ -6,31 +6,40 @@ Base64, TypedArrays, and UTF-8 / Unicode conversions in Browser (and Node) JavaS
This is based wholly on the work by good folks at the MDN.
See <https://developer.mozilla.org/en-US/docs/Web/API/WindowBase64/Base64_encoding_and_decoding>
API

```javascript
// TypedArray <--> UTF8
var uint8Array = Unibabel.strToUtf8Arr(str);
var str = Unibabel.utf8ArrToStr(uint8Array);
// TypedArray <--> Base64
var base64 = Unibabel.arrToBase64(uint8Array)
var uint8Array = Unibabel.base64ToArr(base64)
```
Examples
========
```javascript
// Base64
var myArray = base64DecToArr("QmFzZSA2NCDigJQgTW96aWxsYSBEZXZlbG9wZXIgTmV0d29yaw=="); // "Base 64 \u2014 Mozilla Developer Network"
