Your function will be passed two functions, f and g, that don't take any parameters. Your function has to call them, and return a string which indicates which function returned the larger number.
f returns the larger number, return the string f.g returns the larger number, return the string g.neither.whichIsLarger(() => 5, () => 10) ➞ "g"
whichIsLarger(() => 25, () => 25) ➞ "neither"
whichIsLarger(() => 505050, () => 5050) ➞ "f"
This exercise is designed as an introduction to higher order functions (functions which use other functions to do their work).
