Function combine

Sort an array using multiple compare functions. Elements are sorted which each compare function in the order they were provided. If two elements are equal according to a compare function, the next compare function is used.

Time complexity: O(n)

Space complexity: O(n)

const array = [
  {a: 1, b: 2},
  {a: 1, b: 1},
  {a: 2, b: 2},
  {a: 2, b: 1},
];

array.sort(
  Sort.combine(
    Sort.descending(x => x.b),
    Sort.descending(x => x.a),
  ),
);

console.log(array);
[
  {a: 2, b: 2},
  {a: 1, b: 2},
  {a: 2, b: 1},
  {a: 1, b: 1},
]
