Waa Maxay object?

Sharaxaad

Fikirka waa fudud. Haddaad nationality, age iyo magac saddex variable u kala qorto, isbeddel kastaa waxay kugu qasbaysaa inaad saddexdaba ka shaqayso. Halkii aad saas yeeli lahayd, hal value ayaad isugu geynaysaa oo object ayaad ka dhigaysaa. Kadib developer.age iyo developer.nationality ayaad ku gaadhaysaa, mid kastana magaciisa ayaa kuu sheegaya waxa uu yahay. Taasi waa sababta objects-ku ugu badan yihiin code-ka real ah: user, product, order iyo lesson dhammaantood waa objects.

Hal khalad ayaa jira oo dad badan ku dhaca, gaar ahaan dhinaca React. Markaad object cusub meesha ku beddesho, keys-kii hore way baaba'ayaan. Haddaad rabto inaad hal key beddesho, kuwa kale hana taabanin: { ...developer, age: 23 }. Saddexda dhibcood waxay ka dhigan yihiin "wixii hore ku jiray kaalay", kadibna waxa cusub ayaa la dul saarayaa. Luqadaha OOP sida Python, object micno dheeraad ah ayuu leeyahay: waa shay laga dhalay class, oo xog iyo shaqooyin isku wada haya.

Tusaale

Copy
const developer = { magac: "Xamuud", nationality: "Somaliland", age: 22 };

console.log(developer.age);              // 22
setDeveloper({ ...developer, age: 23 }); // age keliya ayaa beddelmaya

Hal object, saddex qiime. Sadarka labaad wuxuu soo qaadayaa qiimaha, sadarka saddexaadna wuxuu abuurayaa object cusub oo kuwii kale weli sida ay ahaayeen u haya.
