Objects huhifadhi data katika jozi za funguo-na-thamani (key-value pairs). Unahitaji kujua jinsi ya kuzitengeneza na kuzisimamia.

Jinsi ya kutengeneza objects:

1. Object Literals Hii ndiyo njia ya haraka zaidi. let user = { name: "Ezhil", age: 23 };

2. Object Constructor Unatumia neno new hapa. let user = new Object(); user.name = "Ezhil"; user.age = 23;

Operesheni za msingi:

• Kupata sifa Tumia dot notation. console.log(user.name);

• Kusasisha sifa Badilisha thamani moja kwa moja. user.age = 24;

• Kuongeza sifa Weka thamani kwenye funguo mpya. user.job = "Developer";

• Kufuta sifa Tumia neno delete. delete user.job;

• Kuunganisha objects Tumia spread operator ili kuunganisha objects mbili. const merged = { ...obj1, ...obj2 }; Pia unaweza kutumia Object.assign() kuunganisha data.

• Kuangalia urefu wa object Tumia Object.keys() kuhesabu sifa. const length = Object.keys(user).length;

Imarisha misingi hii ili kujenga programu bora zaidi.
