Package-level declarations

The FileList interface represents an object of this type returned by the files property of the HTML element; this lets you access the list of files selected with the element. It's also used for a list of files dropped into web content when using the drag and drop API; see the DataTransfer object for details on this usage.

The FileReaderSync interface allows to read File or Blob objects synchronously. This interface is only available in workers as it enables synchronous I/O that could potentially block.
