import { formdata } from '@muze-nl/metro-formdata'

formdata(...options)

const body = formdata(
  { name: 'Luke' },
  { movie: ['A New Hope', 'The Empire Strikes Back'] }
)

Creates a FormData proxy. Options are applied in order and may be:

• an HTMLFormElement;
• a FormData instance;
• a plain object.

Object values that are arrays append one entry per array item.

const next = body.with({ movie: 'Return of the Jedi' })

with() returns a new formdata value with extra entries. The original value is not changed.
