JS: Array.prototype.toSorted ⭕

(new in ECMAScript 2023)

Array.prototype.toSorted is similar to Array.prototype.sort but returns a copy.

• JS: Array.prototype.sort

// sort array as numbers

const aa = [9, 40, 2];

const bb = aa.toSorted((x, y) => {
 if (x < y) return -1;
 if (x > y) return 1;
 if (x == y) return 0;
});

// original not changed
console.assert(
 JSON.stringify(aa) === "[9,40,2]",
);

console.assert(
 JSON.stringify(bb) === "[2,9,40]",
);
