Sure, but a better name could help a bit. For example, this produces a
'shared' object:

document.getElementById("foo")

while this creates a new one:

myFormElement.getFormData()

It might be ok, but it is a bit inconsistent.

Why not:
formData = new FormData();
formData = new FormData(myFormElement);
