FileReaderSyncThis method reads the contents of the specified Blob or File. When the read operation is finished, it returns an ArrayBuffer representing the file's data. If an error happened during the read, the adequate exception is sent.

The following exceptions can be raised by this method:
NotFoundErrorBlob or File cannot be found, e. g. because it has been erased.SecurityErrorNotReadableErrorEncodingErrorreadAsArrayBuffer in interface FileReaderSyncpublic final String readAsBinaryString(Blob blob)
FileReaderSyncThis method reads the contents of the specified Blob, which may be a File. When the read operation is finished, it returns a DOMString containing the raw binary data from the file. If an error happened during the read, the adequate exception is sent.
readAsArrayBuffer() should be used instead.A DOMString containing the raw binary data from the resource

FileReaderSyncThis methods reads the specified blob's contents. When the read operation is finished, it returns a DOMString containing the file represented as a text string. The optional encoding parameter indicates the encoding to be used. If not present, the method will apply a detection algorithm for it. If an error happened during the read, the adequate exception is sent.
