Kubadilisha Tuple katika TypeScript
Vipengele vya tuple vinaweza kubadilishwa kwa kuandika ndani yao thamani za aina inayofaa. Tuangalie kwa mfano. Hebu tuseme tuna tuple ifuatayo:
let user: [string, number] = ['john', 31];
Wacha tubadilishe kipengele chake:
user[0] = 'eric';
console.log(user);
Lakini jaribio la kuandika kwenye kipengele cha tuple thamani ya aina tofauti kutasababisha hitilafu:
user[0] = 12; // hitilafu
Eleza, matokeo ya utekelezaji wa msururu ufuatao utakuwa nini:
let time: [number, number, number] = [12, 59, 59];
time[0] = 13;
console.log(time);
