// ex:
arr.sort(function compareNumbers(firstNumber, secondNumber){

if a negative number is returned, firstNumber will be the first number in the output
if a positive number is returned, secondNumber will be the first number in the output
if a 0 is returned, it will default to returning them in the position they're already in
*/

// descending order

/*
if firstNumber === 3{
return -1
}
if secondNumber === 3{
return 1
}
return secondNumber - firstNumber
