Sort Array Immutably

📖 Usage Example

const nums = [3, 1, 4, 1, 5]
nums.toSorted((a, b) => a - b)  // → [1, 1, 3, 4, 5]
nums  // → [3, 1, 4, 1, 5]  (unchanged)

Use toSorted() to get a sorted copy of an array without mutating the original.

Array.prototype.toSorted

toSorted returns a new sorted copy of the array without modifying the original — unlike sort, which mutates in place.

Implement sortImmutable that returns a numerically sorted copy of the input array.
