    subject:"Hindi",

    state:"Rajasthan",

    pincode:300000,

const {name,className, subject,asd,pincode} = myObjet;

console.log(name,asd,pincode);

Output::Harry undefined 300000

Example::Second:: Object

const myObjext = {

    name:"Harry",

    className: "five",

    subject:"Hindi",

    state:"rajasthan",

    pincode:123123

function showObject({name, className, subject,state,pincode}){

    const message = "my name is "+name + " I am study in "+className +

    " i like " + subject +" subject most. my state is  "+ state +" ok."
