// sets have no order and only store unique items.
// no need to get data out of a set

const ordersSet = new Set(['Pasta', 'Pizza', 'Risotto', 'Pasta', 'Pizza']);

console.log(ordersSet);

console.log(new Set('Vini'));

// Example

// Working with arrays and sets

const staff = ['Waiter', 'Chef', 'Waiter', 'Manager', 'Chef', 'Waiter'];

const staffUniqueAsASet = new Set(staff);
console.log(staffUniqueAsASet);

// conversion from set to array
const staffUniqueAsAnArr = [...new Set(staff)];
