ArrayArray.prototype.toSortedintermediate

Sort by String Length

📖 Usage Example
const nums = [5, 2, 8, 1]
nums.toSorted((a, b) => b - a)  // → [8, 5, 2, 1]

Pass a comparator to toSorted() to control the sort order without mutating the original.

Array.prototype.toSorted — Custom Comparator

You can pass any comparator function to toSorted, just like sort.

Implement sortByLength which returns a copy of the string array sorted by string length (shortest first).

💡 Hints (2)
  • • Use (a, b) => a.length - b.length as the comparator
  • • toSorted with a comparator works identically to sort with one, but returns a copy
