Kurekebisha Data katika localStorage kwa JavaScript

Inawezekana kurekebisha data iliyohifadhiwa katika kuhifadhi chini ya ufunguo fulani. Hebu tujaribu. Hebu tuandike data fulani:

javascriptlocalStorage.setItem('key', '1');
let value1 = localStorage.getItem('key');

console.log(value1); // itatoa '1'

Sasa turekebishe data hii:

javascriptlocalStorage.setItem('key', '2');
let value2 = localStorage.getItem('key');

console.log(value2); // itatoa '2'
