I have noticed that the estimatedDeliveryTime response from the POST /orders does not use isWeekend().

[antaugustol]

Yes, it does not. But the "skipping weekends part" was an exercise. Lesson 15 Exercise 15m.

@a10n-jsd use this code

const matchedOption = findDeliveryOption(order.orderTime, productDetails.estimatedDeliveryTime);
console.log(matchedOption);

let deliveryDate = 'undefined';
if(matchedOption){
       deliveryDate = calculateDeliveryDateFrom(order.orderTime, matchedOption);
}

 <div class="product-quantity">
     Quantity: ${productDetails.quantity}
 </div>

// all this code for skipping weekends from product-delivery-date
// to skip weekends we need deliveryOptions.deliveryDays 
// but the products we get from backend doesnt have deliveryOption, and we cant change backend
// so here is the code for finding an deliveryOption, which we can use in our function

function countDaysBetween(startDate, endDate) {
    // .diff is built-in method of dayjs which calculates tha difference between two dates in days
    return dayjs(endDate).diff(dayjs(startDate), 'day');
}

function findDeliveryOption(orderTime, estimatedDeliveryTime){
    const daysBetween = countDaysBetween(orderTime, estimatedDeliveryTime);
    return deliveryOptions.find(option => option.deliveryDays === daysBetween) || null;
}

Alternate version of calculateDeliveryDate(). Put this code in deliveryOptions.js

export function calculateDeliveryDateFrom(orderTime, deliveryOption){
    let orderDate = dayjs(orderTime);
    let daysAdded = 0;

    while(daysAdded < deliveryOption.deliveryDays){
        orderDate = orderDate.add(1, 'day');

        //skip weekends: 0 = Sunday, 6 = Saturday
        if(orderDate.day() !== 0 && orderDate.day() !== 6){
            daysAdded++;
        }
    }

    return orderDate.format('MMMM D');
}

this calculates not from current date but the day we ordered

@im-anuj thanks dude!

[DarKnight594]

can you please tell where do we have to put the code you gave above alternate version of calculatedeliverydate?

[im-anuj]

you can put these code at bottom of deliveryOptions.js file, and then can import in order.js and tracking.js

[im-anuj]

if anyone having problems, you can checkout my repo- https://github.com/im-anuj/shopping-site-vanilla
i have done all the assignments and modified it a bit, hope it helps.

[DarKnight594]

Thanks i just put it inside order.js and made it a function so i can export it to tracking.

how do you guys solve the addToCart quantity problem and also the quantity changes after clicking 'buy again' button ?

[ceb07]

` addToCart(productId){
let matchingItem;

this.cartItems.forEach((cartItem) => {
  if(productId === cartItem.productId){
    matchingItem = cartItem
  }
});

const quantitySelector = document.querySelector(`.js-quantity-selector-${productId}`)
const quantity = Number(quantitySelector.value)

if(matchingItem){
  matchingItem.quantity += quantity
}else{
  this.cartItems.push({
    productId,
    quantity,
    deliveryOptionId: '1'
  })
}

this.saveToStorage()

}`

this is my addToCart code inside the cart Class

Hi. I had published the project on github and deployed it through github pages. After some time, they disabled my repository. Any idea why this happened? It says i violated GitHub Trademark policy

Hey, same thing happened to me recently!
I had uploaded this project, and GitHub disabled the repo saying it violated their trademark policy.

What worked for me:

Renamed the repo (removed "Amazon" from the name)

Added a visible disclaimer (like a alert/popup saying it's just an educational project)

Then I contacted GitHub here: https://support.github.com/contact/reinstatement
They gave me 3 days to fix it and reinstated the repo after that.

Hope this helps!

[DarKnight594]

Thanks, I'll check it out. I had uploaded it as Amazon_Project so I guess I will change that. But how do I make sure the site doesn't collect data. Do I need to remove localstorage?

[DarKnight594]
