Basically I was trying to access the properties of an object in JavaScript and than I thought If i can access the array values present inside the object

// Object
let user={
  name:"rajat",
  age:23,
  email:["ag.112","ag.113"]
};

now for accessing particular elements of an array I am not able to understand how to do this

console.log(user);
console.log(user.name);
console.log(user.age);
console.log(user['age']);

like I want to access the 2nd element present inside the email(ag.113) In JavaScript

    Try `user.email[1]` for that. Objects are key-value pair, so dot(`.`) makes sence horever, arrays are indexed and hence you will have to use `position` of element where first position is 0 – Rajesh Dec 18 '19 at 11:15

  • You can post your comment as an answer It was enough than I can mark it as an answer and thanks for clearing my doubt I just started learning JavaScript @Rajesh – Rajat Agrawal Dec 18 '19 at 11:21
  • You need to select property first and then select element which you need (array iteration started from 0) `user.email[1]` – demkovych Dec 18 '19 at 11:22
  • You can write a simple callback function --> let user={ name:"rajat", age:23, email:["ag.112","ag.113"] }; user.email.forEach(function(arr) { console.log(arr); }); – DESH Dec 18 '19 at 11:32

I don't know if that's what you mean, but you can do :

numb = 0/1

user.email[numb]

to get the contents of "email"; or you can do 

user[email][numb]

i wrote a simple function to handle those easy and putting them into local Storage:

function getlist(option, name, listid, must, childnam, contenta, contentb) {

    if (list != 1) {
        if (option != "help") {
            var listid = "produkte";
            var list = JSON.parse(localStorage.getItem(listid));



            console.log(list)

            var allleng = _.size(list);



            console.log(cont);
            switch (option) {
                default: var child = list;

                return child;
                break;
                case "get":
                        var child = list[name];

                    return child;
                    break;
                case "pardel":
                        var child = list[name];
                    var leng = _.size(child);
                    var cont = child[childnam];
                    delete list[name];
                    localStorage.setItem(listid, JSON.stringify(list));
                    return list;
                    break;

                case "setpar":

                        list = _.extend(list, _.object([
                        [contenta, {}]
                    ]));
                    localStorage.setItem(listid, JSON.stringify(list));
                    return list;

                    break;
                case "set":

                        list = _.extend(list, _.extend(list[name], _.object([
                        [childnam, contenta],
                        [(childnam + "must"), must]
                    ])));

                    localStorage.setItem(listid, JSON.stringify(list));
                    return list;
                    break;
                case "setchild":

                        list[name] = _.extend(list, _.extend(list[name], _.object([
                        [childnam, _.object([

                        ])]
                    ])));

                    localStorage.setItem(listid, JSON.stringify(list));
                    return list;
