    Just an additional proposed improvement to improve readability (not critical): it will be great if blob/array buffer writing logic is wrapped to separate functions (writeArrayBufferAsync/writeBlobAsync), similar to
    Windows.Storage.FileIO.writeBytesAsync
    Windows.Storage.FileIO.writeTextAsync
    
    So we can continue using logic with writePromise:
    
    if (data instanceof ArrayBuffer) {
        writePromise = writeArrayBufferAsync;
    } else if (data instanceof Blob) {
        writePromise = writeBlobAsync;
    } else if ...

> When trying to save Blob using FileWriter.write method, if the blob's size is too high, we get a stack overflow exception during the conversion of the blob into an basic array.
> WinRT (WinJS) provide a method to write Blob directly to the filesystem. It uses Streams so it's safe for memory.

> Method : writeBlobToFile
