Create an array of numbers and sort the numbers in ascending and descending order based on a choice using switch case in javascript code example

Example 1: js sort numbers descending order

// Sort Numbers in Descending Order
function sortDescending(num) {
	return Number(num.toString().split('').sort((a, b) => b - a).join(''));
//or: return parseInt(num.toString().split('').sort().reverse().join(''));
}

console.log(sortDescending(123)); // 321
console.log(sortDescending(1254859723)); // 9875543221

Example 2: javascript sort numbers descending

var numArray = [140000, 32, 12, 63323, 104, 99];

numArray.sort(function(a, b) {
  return b - a;
});

// Array(6) [ 140000, 63323, 104, 99, 32, 12 ]
