Using spread operators to get data from arrays
// In our restaurant, the chef has some favourite dishes in two different categories.
// The chef loves all dishes that start with "S", while the rest are regular dishes
// Use array destructoring to create arrays of the chefs favourite dishes of meat and
// fish, and to create arrays of the regular meat and fish dishes

const fishDishes = ['Salmon Rillettes', 'Grilled Tuna Provencal', 'Fish and Chips']
const meatDishes = ['Lasagna', 'Spaghetti', 'Satay Chicken Skewers']

// Modify these four variables first
let [chefsFishDishes, ...regularFishDishes] = fishDishes;

let [regularMeatDishes ,...chefsMeatDishes] = meatDishes;

// console.log(chefsFishDishes);
// console.log(regularFishDishes);
// console.log(regularMeatDishes);
// console.log(chefsMeatDishes);

// Finally, use the spread operator to create these two arrays as well
let chefsDishes = [...chefsMeatDishes, chefsFishDishes]
let regularDishes = [...regularFishDishes, regularMeatDishes];
console.log(chefsDishes);
console.log(regularDishes);

Of course you can use findByIndex but this is intended to explain spread operators
