Kubadilisha Miundo ya Data ya JavaScript kuwa Umbo la JSON

Kwa kutumia njia JSON.stringify inawezekana kubadilisha safu na vitu vya JavaScript kuwa umbo la JSON. Hebu tuangalie kwa mfano.

Tuchukulie tuna safu yenye data:

javascriptlet arr = [1, 2, 3, 4, 5, 'a', 'b'];

Wacha tubadilishe safu yetu kuwa mfumo wa maneno:

javascriptlet json = JSON.stringify(arr);
