File()

The File() constructor creates a new File object instance.

Inputs: fileBits An iterable object such as an Array, having ArrayBuffers, TypedArrays, DataViews, Blobs, strings, or a mix of any of such elements, that will be put inside the File. Note that strings here are encoded as UTF-8, unlike the usual JavaScript UTF-16 strings. fileName A string representing the file name or the path to the file. options An options object containing optional attributes for the file. Available options are as follows: type A string representing the MIME type of the content that will be put into the file. Defaults to a value of “”. endings How to interpret newline characters (n) within the contents, if the data is text. The default value, transparent, copies newline characters into the blob without changing them.
