JSON ma'lumotlarini JavaScriptda o'zgartirish

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

javascriptlet 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:

javascriptlet arr = JSON.parse(json);

Massivga yangi element qo'shamiz:

javascriptarr.push(6);

O'zgartirilgan massivni qaytadan JSON ga aylantiramiz:

javascriptlet res = JSON.stringify(arr);

Yakuniy kod quyidagicha ko'rinadi:

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

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

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

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

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

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