Massivlarni satrlarga aylantirish

JavaScript usuli toString()massivni (vergul bilan ajratilgan) massiv qiymatlari qatoriga aylantiradi.

Misol

const fruits = ["Banana", "Orange", "Apple", "Mango"];
document.getElementById("demo").innerHTML = fruits.toString();
Natija:
Banana,Orange,Apple,Mango
join() barcha massiv elementlarini satrga birlashtiradi.
U xuddi toString() kabi ishlaydi, lekin qo'shimcha ravishda siz ajratuvchini belgilashingiz mumkin:

Misol

const fruits = ["Banana", "Orange", "Apple", "Mango"];
document.getElementById("demo").innerHTML = fruits.join(" * ");
Natija:
Banana * Orange * Apple * Mango

JavaScript massivi pop()

Pop() massivdan oxirgi elementni olib tashlaydi:

Misol

const fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.pop();
pop() "chiqarilgan" qiymatni qaytaradi:

Misol

const fruits = ["Banana", "Orange", "Apple", "Mango"];
let fruit = fruits.pop();

JavaScript Array push()

push()massivga yangi element qo'shadi (oxiridan):

Misol

const fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.push("Kiwi");
push()yangi massiv uzunligini qaytaradi:

Misol

const fruits = ["Banana", "Orange", "Apple", "Mango"];
let length = fruits.push("Kiwi");

JavaScript massivini siljitish()

shift()massivning birinchi elementini olib tashlaydi va qolgan barcha elementlarni pastki indeksga "o'tkazadi".

Misol

const fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.shift();
shift()"o'chirilgan" qiymatni qaytaradi:

Misol

const fruits = ["Banana", "Orange", "Apple", "Mango"];
let fruit = fruits.shift();
