Description Domenic Denicola 2017-03-27 22:52:30 PDT 
Spec change: https://github.com/whatwg/html/commit/688a102b52c7050a6808a05c5d8fe149c0937fd7
Tests: http://w3c-test.org/html/editing/dnd/datastore/datatransfer-constructor-001.html

This is part of a larger feature for async clipboard APIs; see discussion in https://github.com/w3c/clipboard-apis/issues/33. But it can be implemented independently.

This constructor will also allow the instanciation of a FileList (it currently works on Firefox / Chromium)

Without this API it's impossible to create a FileList from a File array 

  const data = new DataTransfer() // This is not working on webkit
  files.forEach(file => data.items.add(file))
  return data.files

The only real usecase i see with having a DataTransfer constructor is having a way to update that damm input[type=file] with another FileList item. 

there is no way of getting it in safari...

new ClipboardEvent('paste').clipboardData
new DragEvent('drag').dataTransfer
new DataTransfer()
