Making a date to my products so i can remove them via it

so im stuck…I have this assignment to add products to a shoppingcart and store them in local storage which i have done, but i use splice so if I have 2 similiar products it will remove the first one, which is kind of logical, but I think i need to have a date so my remove function knows.

i have a json file that looks like this:

    "phones": [
            "title": "iPhone X",
            "description": "Last years phone from Apple with a beautiful all display front.",

            "title": "Samsung Galaxy S9 plus",
            "description": "Galaxy S9 is the company's flagship smartphone for 2018.",

and my add function looks like this:

/* creating localstorage and storing products */
var shoppingCart = [];
var ulElement;

if(localStorage.shoppingCart) {
    shoppingCart = JSON.parse(localStorage.shoppingCart);

function addPhones(product) {  
    var phoneArray = JSON.stringify(shoppingCart);
    localStorage.shoppingCart = phoneArray;
// adds products to cart page//
function initSite() {
/* here is a printProductsInCart function that I call in i initSite to count the sum of phones added */
function printProductsInCart() {
    document.getElementById("wrapperForAllPhones").innerHTML = ""
    document.getElementById("sumOfProducts").innerHTML = "Din varukorg är tom!" 
    var totalPrice = 0;
    var shoppingCartItems = JSON.parse(localStorage.shoppingCart);
    for(var i = 0; i < shoppingCartItems.length; i++) { 
        totalPrice += shoppingCartItems[i].price;
    $('#sumOfProducts').text("Totalt pris: " + totalPrice + " kr");
    for (i = 0; i < shoppingCart.length; i++) {
        var createPhone = createPhoneCard(shoppingCart[i])


/* deletProducts form cart page */ here is the delet products function :slight_smile:

function deletePhone(product) {
    if (localStorage.clickcount) {
        localStorage.clickcount = Number(localStorage.clickcount) - 1;
        document.querySelector(".number-of-orders").innerHTML = localStorage.clickcount;
    //var tempShopingCart = []
    for (var i = 0; i < shoppingCart.length; i++) {
        if (product.title == shoppingCart[i].title) {
            shoppingCart.splice(i, 1)
    var phoneArray = JSON.stringify(shoppingCart);
    localStorage.shoppingCart = phoneArray;

Please format your code by wrapping them between ``` (three backticks). Also I didn’t see any remove function, what you have done already?

i have done it :slightly_smiling_face: please check it out !

So you want to put a date in your object when it is added to the shopping cart? Then when it’s time for remove you can remove the first added?

To create a date, just do new Date() when the object is added to the shopping cart. I will write some example code just to show how you could do:

shoppingCart.push({...product, dateInserted: new Date()});

In the deletePhone function you could sort by the dateInserted and remove the first one.

shoppingCart.sort((a, b) => -
// then removes the first one

Note that I didn’t run any of this code, just to give you an idea.
