javascript sort by number descending code example

Example 1: javascript ascending and descending

// ascending and discending for number
const arr1 = [21, 2100, 2, 35000];
const arr2 = [21, 2100, 2, 35000];

let ascN = arr1.sort((f, s) => f - s);
let dscN = arr2.sort((f, s) => s - f);

// ascending and discending for string
const arr3 = ['21', '2100', '2', '35000'];
const arr4 = ['21', '2100', '2', '35000'];

let ascS = arr3.sort((f, s) => f.length - s.length);
let dscS = arr4.sort((f, s) => s.length - f.length);

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 ]
