Babel.js iterable FileList

iterableFileList.js

function iterableFileList(fileList) {
  return Object.assign({
    __proto__: fileList.__proto__,
    [Symbol.iterator]() {
      let nextIndex = 0;
      return {
        next() {
          return nextIndex < fileList.length ?
            {done: false, value: fileList[nextIndex++]} :
            {done: true};
        }
      }
    }
  }, fileList)
}

You can iterate over file list like that:

for (var file of iterableFileList(fileList)) {
  …
}

…or you can simply iterate over Array.from(fileList)
