JSON ma'lumotlarini JavaScriptda o'zgartirish

Faraz qilaylik, bizda JSON formatidagi massivni o'z ichiga olgan satr mavjud:

let json = '[1, 2, 3, 4, 5]';

Keling, ushbu massivning oxiriga yana bitta element qo'shamiz. Buning uchun biz bir qator bosqichlarni bajarishimiz kerak.

Boshlash uchun JSON ni JavaScript massiviga aylantiramiz:

let arr = JSON.parse(json);

Massivga yangi element qo'shamiz:

arr.push(6);

O'zgartirilgan massivni qaytadan JSON ga aylantiramiz:

let res = JSON.stringify(arr);

Yakuniy kod quyidagicha ko'rinadi:

let json = '[1, 2, 3, 4, 5]';

let arr  = JSON.parse(json);
arr.push(6);

let res = JSON.stringify(arr);
console.log(res);

Quyidagi JSON berilgan:

let json = '["user1","user2","user3","user4","user5"]';

Satr oxiriga yana bitta foydalanuvchi qo'shing.

Quyidagi JSON berilgan:

let json = '["user1","user2","user3","user4","user5"]';

Ikkinchi foydalanuvchi ismini o'zgartiring.

Quyidagi JSON berilgan:

let json = `[
	{
		"name": "user1",
		"age": 25,
		"salary": 1000
	},
	{
		"name": "user2",
		"age": 26,
		"salary": 2000
	},
	{
		"name": "user3",
		"age": 27,
		"salary": 3000
	}
]`;

Ushbu satrga yana bitta xodim qo'shing.
