Sort multi array by number javascript [duplicate]

Question

I have this multi array with a url and number in each inner array, how do i sort so the array is organized by highest number to smallest.

var arr = [
["http://example.com", "3"],
["http://example.com2", "1"],
["http://example.com3", "22"]
]

i want it to look like this

var arr = [
["http://example.com3", "22"],
["http://example.com", "3"],
["http://example.com2", "1"],
]

You can use .sort function with custom compareFunction, like this

var arr = [
  ["http://example.com", "3"],
  ["http://example.com2", "1"],
  ["http://example.com3", "22"]
];

var res = arr.sort(function (a, b) {
  return b[1] - a[1];
});

console.log(res);
