Clonare un Array

const sourceArray = [1,2,3];
// Via spread operator
const clonedArray = [...sourceArray];
// Via metodo slice
const clonedArray = sourceArray.slice();

Sappiamo però che in JavaScript in fase di assegnazione le variabili di tipo Array (ed anche gli Oggetti) vengono passate per riferimento e quindi quello che può accadere è che più variabili possano puntare alla stessa struttura dati!
