Given an array of integers and a target value, return the number of pairs of array 
elements that have a difference equal to a target value.


Examples:
$ arrayDiff([1, 2, 3, 4], 1)
$ 3 // 2 - 1 = 1, 3 - 2 = 1, and 4 - 3 = 1

// Crunchbase hides search results behind a darker element and blurs the rows. This removes that
// so you can see the top 15 results instead of just 5. Though you won't be able to see beyond that.

// An example race condition in JavaScript
// When you run this script using Node or in a browser, you'll find it
// does not print "Ended with 0", but a random number. Even though the functions running
// simply loop 100 iterations of adding and subtracting. The reason the end result is random
// is because the sleeps are of random duration and the time between the read of the variable
// causes the eventual write to be incorrect when `adder` and `subber` interleave.
// This problem is similar to https://en.wikipedia.org/wiki/Time-of-check_to_time-of-use

let number = 0;
