Kubadilisha Data katika JSON kwa JavaScript

Tuchukulie tuna mfuatano unao vyombo vya habari katika umbizo la JSON:

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

Wacha tuongeze kwenye mwisho wa vyombo vya habari hivi kipengele kingine. Kwa kufanya hivyo tunahitaji kufanya hatua kadhaa.

Kwa kuanza tufungue JSON kwenye vyombo vya habari vya JavaScript:

javascriptlet arr = JSON.parse(json);

Tuongeze kwenye vyombo vya habari kipengele kipya:

javascriptarr.push(6);

Tubadilishe vyombo vya habari vilivyobadilishwa kurudi kwenye JSON:

javascriptlet res = JSON.stringify(arr);

Msimbo wa mwisho utaonekana kama ifuatavyo:

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
  }
]`;
