File() constructor in IE and Safari

Question

The File() constructor is not supported in IE and Safari.CanIUse

Is there a nice solution to this in Angular/JavaScript?

var file = new File(byteArrays, tempfilename, { type: contentType });

Could I create the file in other ways, that is supported by IE an Safari?

Please clarify what exactly isn't supported or what solution you'd want to an unsupported feature. — deceze, Jun 09 '15 at 08:47

If you absolutely want or need to use the File API, there's mOxie polyfill suggested by CanIUse.

I solved the problem today by creating a blob instead. FileReader is supported by all browsers. – Delete me Jun 12 '15 at 10:00
