Katika kazi zifuatazo programu fulani aliandika msimbo na labda, alifanya makosa ndani yake. Unapaswa kuangalia, kama msimbo unafanya kile kilichoelezewa. Ikiwa msimbo unafanya kazi vibaya, unapaswa kurekebisha makosa.
Msimbo unapaswa kuchapisha kipengele cha mwisho cha safu:
let arr = [1, 2, 3, 4, 5];
console.log(arr[arr.length - 1]);
Msimbo unapaswa kupata jumla ya vipengele vya safu:
let arr = [1, 2, 3, 4, 5];
console.log(arr[0] + arr[1] + arr[2] + arr[3] + arr[4]);
Msimbo unapaswa kuchapisha urefu wa safu:
let arr = [1, 2, 3, 4, 5];
console.log(arr.length);
