Blob.js
==============

Blob.js implements the W3C [`Blob`][1] interface in browsers that do
- Blob.js implements the Blob, File, FileReader and a subset of URL interface in browsers that do
not natively support it.
- Adds the new reading methods
- `blob.text()` A promise resolving into text
- `blob.arrayBuffer()` A promise resolving to `ArrayBuffer`
- `blob.stream()` returns a ReadableStream (Made of ReadableStream or `new Response(blob).body`
- It monkey patches `XMLHttpRequest.prototype.send` to support sending blobs while making sure Content-Type is set in old IE that didn't send blob's type
- It override existing File implementation if they are not constructable (Old Safari & IE mainly)
- `URL` get unprefixed
- `URL.createObjectURL` creates a base64 data url if it's a "fake" Blob

Supported browsers
------------------
Notes
------------------
ArrayBuffer, Promise and the Stream api's are not added, We recommened you to include polyfills for those if you plan to use them.
`readAsArrayBuffer` and `arrayBuffer()`: returns a regular array if typed arrays are not supported.

Blob.js shares the [same supported browsers as FileSaver.js][2].

Fairly far back as it's uses very old syntax.
