Research direction
Review the linked Formatting Inputs example and the shown formatPhoneNumber line. Clarify what the function syntax means, how spaces are added, and how the value prop is handled; it is done when the example answers the reporter’s questions directly.

Description
In this example Formatting Inputs I'm confused by this line:
const formatPhoneNumber: string => string = (unformattedPhoneNumber) => ...;
Why the double function indirection? How exactly is that adding spaces? I'm guessing it's just a sample to say that if "value" prop is a function, it'll get called but store the value untransformed.
Would love some hints.
