CONSTRUCTOR IN JAVASCRIPT

CONSTRUCTOR
The constructor in JavaScript is automatically called when the object is created. Constructor name should be start in the uppercase. Constructor is a initialization object specific value. It will reduce the repetition line of object creation.

NORMAL OBJECT CREATION

const tv1={
price:50000,
brand:"samsung"
}
const tv2={
price:60000,
brand:"Sony"
}
const tv3 ={
price:70000,
brand:"LG"
}

In this code the price and brand are repeated in all the object so instead of these we can use the constructor to reduce the code

CONSTRUCTOR

const tv1= new Tv(50000,"samsung");
const tv2= new Tv(60000,"Sony");
const tv3= new Tv(70000,"LG");

function Tv(price,brand){
this.price=price;
this.brand=brand;
}

In these code the function will call automatically once the object is created.
"this" refer to the current object
