isPerfect.js
Create a function isPerfect() that takes a number and returns true if it's perfect, and false otherwise.
A perfect number is a positive integer that is equal to the sum of its proper positive divisors excluding the number itself. For example, 6 is perfect, because 6 = 1 + 2 + 3.
isPerfect(6); // true
isPerfect(7); // false
