Object in JavaScript

• Object used to store multiple values in single container
• Object is a physical Entity
• It contains in formations,properties and key values
• To differentiate object and property we can use . operator
• Also object contains State and behaviour
• Object contains another object in nested way

(e.g)

const bike={
Brand:"Yamaha Rx 100",
Colour : "Black",
price:1,00000
}
console.log(Bike.price);
Output:1,00000

Explanation

• In this type bike is a object,Brand ,colour ,price are keys for object and Yamaha Rx 100,Black,1,00000 are values.
• To print a bike price declare function and call price
• This print a bike's price

NESTED OBJECT:

const Samsung={
mobile: "S 23 ultra",
price: 1,00000,
colour:"black",
camera:{
rear:{
mp:"50 mp"
}
front:{
mp:"22 mp"
}
},
checking camera mp.function(){
console.log(samsung.camera.rear);
}
};

OUTPUT:50 mp

• This is how nested objects works and execute

Adding a value in object
let student={
name:"Akash",
age:22,
weight:"62 kilogram"
};
student.age=23;
console.log(student.age);

OUTPUT:23

Deleting a Value in object
let student={
name:"Akash",
age:22,
weight:"62 kilogram"
};
delete student.weight;
console.log(student);

OUTPUT:
{name:"Akash",age:22}
