Constructor Function ,Methods in JS

• Constructor function is usually started with capital letter
• It used with new keyword
• It helps to create object without repeating code

(e.g)
function Bike(model,price,colour)
{
this.model=model;
this.price=price;
this.colour=colour;
console.log(this.bike1.colour);
console.log(this.bike2.model);

}
const bike1=new bike("RX 100",100000,"black");
const bike2=new bike("Royal Enfield",200000,"grey");

OUTPUT:Black
Royal Enfield

EXPLANATION:

1. Declaring function() bike
2. In construction function this is used as a keyword for identifying specific value
3. Declaring values for function
4. print a needed variable using this (this is used for indicating particular function)
