Obektlarning xususiyatlari.!!!

Obektning xususiyatiga kirish.! obektning xususiyatiga kirish sintaksisi: objectName.property objectName["property"]

const car={
    type:"BMW",
    price:"50000$",
    wight:"1500kg",

let result1=car.type;
console.log(result1);
// natija - BMW

let result2=car["price"];
console.log(result2);
//natija - 50000$

yangi xususiyat qo'shish
sintaksis: objectName.key="newValue"

const person={

// add new property
person.age=21;

console.log(person);
// natija - {fName: 'samandar', lName: 'hodiev', job: 'programmer', age: 21}

Xususiyatlarni o'chirish
