// you should know that there are two major types of datatypes in js

//on basis of how data is stored and accessed we divide data types that is

//premetives and non premetives

//premetives ==call by value, gives copy , nonpre==call by reference, gives original

//premetive ==7 no,string,bigint,undefined,null, boolean, symbol(that uniquely identify component)

//nonpre== obj , array , function

// js is dynamic language because dt is determine by what value they old at runtime

//==================================codetime======================================================

//array

let array1=['ahmed',5,'bilal']

let array2=['3','ayesha']

console.log(array1,array2)

//object its just like structure in c

let obj1={

name:'saman',

age:29

}

console.log(obj1)

// function not working now

const fun1=function(){

console.log('hello world')

}
