# --description--
Given two [set](https://rosettacode.org/wiki/set)s *A* and *B*, compute $(A \\setminus B) \\cup (B \\setminus A).$ That is, enumerate the items that are in *A* or *B* but not both. This set is called the [symmetric difference](https://en.wikipedia.org/wiki/Symmetric difference) of *A* and *B*. In other words: $(A \\cup B) \\setminus (A \\cap B)$ (the set of items that are in at least one of *A* or *B* minus the set of items that are in both *A* and *B*).
Dati due [insiemi](https://rosettacode.org/wiki/set) *A* e *B*, calcola $(A \\setminus B) \\cup (B \\setminus A). Vale a dire elenca gli elementi che sono in *A* o *B*, ma non in entrambi. Questo insieme è chiamato la [differenza simmetrica](https://en.wikipedia.org/wiki/Symmetric difference) di *A* e *B*. In altre parole: $(A \\cup B) \\setminus (A \\cap B)$ (l'insieme di elementi che sono in almeno uno di *A* o *B* meno l'insieme di elementi che sono sia in *A* che in *B*).
# --instructions--
Write a function that takes two arrays as parameters and returns the symmetric difference. Sort the resultant array before returning it.
Scrivi una funzione che prende due array come parametri e restituisce la differenza simmetrica. Ordina l'array risultante prima di restituirlo.
# --hints--
`symmetricDifference` should be a function.
`symmetricDifference` dovrebbe essere una funzione.
```js
assert(typeof symmetricDifference == 'function');
```
`symmetricDifference(["John", "Bob", "Mary", "Serena"], ["Jim", "Mary", "John", "Bob"])` should return an array.
