FormData.entries()

The FormData.entries() method returns an iterator which iterates through all key/value pairs contained in the FormData. The key of each pair is a string, and the value is either a string or a Blob.

Note: Unlike Map entries, FormData entries are not necessarily unique by key. A form can contain multiple elements with the same name, so the same key may appear in more than one pair while iterating. Past the first entry, the value may differ from the return value of get() which returns the first value associated with the key.
