Compare JSON.stringify of arrays/objects to JSON.stringify of the expected value:\n 1. uniqueBy([], x => x) yields [] (JSON.stringify(result) === \"[]\")\n 2. uniqueBy([1, 2, 2, 3, 3, 3], x => x) yields [1, 2, 3]\n 3. uniqueBy([5, 4, 4, 5, 3], x => x) yields [5, 4, 3]\n 4. uniqueBy([\"a\", \"b\", \"a\"], x => x) yields [\"a\", \"b\"]\n 5. uniqueBy([{id:1},{id:2},{id:1},{id:3}], x => x.id) yields [{id:1},{id:2},{id:3}]\n 6. uniqueBy([\"apple\",\"banana\",\"avocado\",\"blueberry\"], x => x[0]) yields [\"apple\",\"banana\"]\n 7. uniqueBy([10, 20, 30], x => Math.floor(x / 10)) yields [10, 20, 30]\n 8. uniqueBy([10, 11, 12, 20, 21], x => Math.floor(x / 10)) yields [10, 20]\n 9. const nums = [1, 1, 2]; uniqueBy(nums, x => x); then JSON.stringify(nums) === \"[1,1,2]\" (input not mutated)\n 10. uniqueBy([\"x\",\"X\",\"x\",\"y\"], x => x.toLowerCase()) yields [\"x\",\"y\"]\n\nAcceptance criteria (how the creator will verify):\n1.
