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

Njia za kutengeneza objects:

1. Object Literal Tumia mabano ya {} (curly braces) ili kufafanua data moja kwa moja. let user = { name: "Ezhil", age: 23 };

2. Object Constructor Tumia neno new. let user = new Object(); user.name = "Ezhil";

Operesheni za kawaida:

• Kupata data Tumia dot notation kusoma thamani. console.log(user.name);

• Kubadilisha data Weka thamani mpya kwenye funguo (key) iliyopo. user.age = 24;

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

• Kufuta data Tumia neno delete. delete user.age;

• Kuunganisha objects Unganisha objects mbili kwa kutumia spread operator. const combined = { ...obj1, ...obj2 };

Pia unatumia Object.assign() kuunganisha objects kwenye object lengwa.

• Kuangalia ukubwa Tumia Object.keys() kupata idadi ya sifa (properties). const size = Object.keys(user).length;
