I have the following FormData object and I want to access the value of the filename. I believe that it is decoded. How would I get the value of the filename field?

{
  fieldname: 'wavfile',
  originalname: '412.wav',
  encoding: '7bit',
  mimetype: 'application/octet-stream',
  destination: 'uploads/',
  filename: '8e7ca142ba91e211f3dfa52b77d7c6ee',
  path: 'uploads/8e7ca142ba91e211f3dfa52b77d7c6ee',
  size: 435268
}
