/* key value pairs
no need of index to access data*/

//creating an object
const person={
    firstName:"Erem",
    lastName:"Yeager",
    favNum: 8,
    favColors:["blue","green"]
}

//accesing objects by their KeyName
person["firstName"]; //dont forget the quotes, js converts the keynames to strings
person.firstName;//now forget it

//creating a variable pointing to a string using the data of person
let tatakae=person["firstName"]+person["lastName"];

//modifying objects
person.favNum=9; //u can also insert something of a different datatype
person["firstName"]="Zeke";
person["Father"]="Grisha"; //adding key value pairs
