Details

I'm not sure if this is intentional. It seems rather strange to me.
Code example:

const reader = new FileReader();
reader.onerror = errorEvent => {
  // errorEvent is not helpful at all.
  // Need to check reader.error.name instead.
};
reader.readAsArrayBuffer(someBlob);

This is correct. You should use FileReader.error in order to have a DOMError object.
