Returns the unique symmetric difference between two arrays, not containing duplicate values from either array.
- Use `Array.prototype.filter()` and `Array.prototype.includes()` on each array to remove values contained in the other, then create a `Set` from the results, removing duplicate values.
- Use `Array.prototype.filter()` and `Array.prototype.includes()` on each array to remove values contained in the other.
- Create a `new Set()` from the results, removing duplicate values.
```js
const uniqueSymmetricDifference = (a, b) => [
...new Set([...a.filter(v => !b.includes(v)), ...b.filter(v => !a.includes(v))])
...new Set([
...a.filter(v => !b.includes(v)),
...b.filter(v => !a.includes(v)),
]),
];
