🚀 Unlocking the Power of Array Destructuring in JavaScript 🚀

🔗 Array destructuring is a useful technique that enables you to easily extract values from arrays and assign them to variables in a single line of code. This approach eliminates the need for verbose indexing and makes it easier to access and work with array elements.

🌟 Key Benefits:

1. Readability: Destructuring makes your code more readable by clearly indicating which values you're interested in.
2. Conciseness: It reduces boilerplate code and simplifies assignments.
3. Multiple Assignments: You can easily swap or reassign values between variables.
4. Default Values: You can provide default values for variables to handle undefined array elements.

// destructuring basically a way of unpacking values from an array or an object into separate variables. So in other words destructuring is to breka a complex data structure down  into a smaller data structure like a variable.

const resturant = {
  name: "Classico Italiano",
  location: "Via Angelo Travanti 23, Firenze , Italy",
  catagories: [
    "Italian",
    "Pizzarea",
    "Vegeterian",
    "Garlic",
    "Organic",
    "Natural",
  ],

  StarterMenu: ["Bread", "Burger", "Pizza", " HotSnda ", "Pastalua"],

  mainMenu: ["Coffee", "Burger", "Pastsa", "Ristorica"],

  order: function (startterIndex, mainIndex) {
    return [this.StarterMenu[startterIndex], this.mainMenu[mainIndex]];
  },
};

console.log(resturant);

//switching variable with array distruturing......
let [main, , secondary] = resturant.catagories;
console.log(main, secondary);

[secondary, main] = [main, secondary];
console.log(main, secondary);

//receive 2 return values from a function
console.log(resturant.order(2, 1));

const [start, mainn] = resturant.order(2, 1);
console.log(start, mainn);

//******************* */
//Nested Array
console.log("*****start nested array***");

const nested = [1, 2, 4, [5, 6]];
const [i, , , j] = nested;
console.log(i, j);

//We can also set default values for the variables when we are extracting them. And that's gonna be very useful in the case that we don't know the length of the array, this can sometimes happen in real world applications.

//if we have an array that is shorter than we might think, then we migh try to unpack the array in position that don't even exist. 

const [p , q , r = 20 ] = [8,9];
console.log(p,q,r);
