Kuvunja Vikundi vya Map Kwa Kutumia Kitanzi
Tuchukulie tuna kikundi cha Map:
let map = new Map;
let arr1 = [1, 2];
let arr2 = [3, 4];
map.set(arr1, 'data1');
map.set(arr2, 'data2');
Kikundi hiki kinaweza kuvunjwa kwa kutumia kitanzi
for-of:
for (let elem of map) {
}
Wakati huo, ndani ya elem zitaingia safu
za jozi ufunguo-thamani. Katika kipengele cha kwanza
kitakuwa na ufunguo, na cha pili - thamani:
for (let elem of map) {
console.log(elem); // kwanza [[1, 2], 'data1'], kisha [[3, 4], 'data2']
}
Inawezekana kutenganisha funguo na thamani kwa kutumia destructuring:
for (let [key, elem] of map) {
console.log(key);
console.log(elem);
}
