Kuvunja Vikundi vya Map Kwa Kutumia Kitanzi

Tuchukulie tuna kikundi cha Map:

javascriptlet 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:

javascriptfor (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:

javascriptfor (let elem of map) {
  console.log(elem); // kwanza [[1, 2], 'data1'], kisha [[3, 4], 'data2']
}

Inawezekana kutenganisha funguo na thamani kwa kutumia destructuring:

javascriptfor (let [key, elem] of map) {
  console.log(key);
  console.log(elem);
}
