Kiterenji cha ndani cha entries katika JavaScript

Vitu vyote vinavyoweza kuandikwa kwa mfululizo vina kiterenji cha ndani entries, kinachoruhusu kupitia jozi za ufunguo-thamani. Hebu tukikagua kwenye safu:

javascriptlet arr = ['a', 'b', 'c'];

Tupate kiterenji:

javascriptlet iter = arr.entries();

Tukiipite kwa kitanzi:

javascriptfor (let entry of iter) {
  console.log(entry); // [0, 'a'], [1, 'b'], [2, 'c']
}

Tufanye udestructurization wakati wa kupitia:

javascriptfor (let [key, value] of iter) {
  console.log(key);   // 0, 1, 2
  console.log(value); // 'a', 'b', 'c'
}
