Description

When the item in a list is checked (i.e. purchased), the firebase.js updates the item's dateNextPurchased property. In the updateItem function, the calculateEstimate function is used to calculate the date of the next purchase.

Acceptance Criteria

• When the user purchases an item, the item’s dateNextPurchased property is calculated using the calculateEstimate function and saved to the Firestore database
  • dateNextPurchased is saved as a date, not a number
• A getDaysBetweenDates function is exported from utils/dates.js and imported into api/firebase.js
  • This function takes two JavaScript Dates and return the number of days that have passed between them

There are no UI changes.

Testing Steps / QA Criteria

1. npm start
2. Start app in the browser.
3. Navigate to ManageList view
4. Add an item to a list
5. Navigate to the Firebase console and check the newly-created item's dateNextPurchased
6. Go back to the browser and check the item as purchased in the List view
7. Corroborate the updated item in the Firebase console. The dateNextPurchased in the document should be updated based on the time elapsed between the item's creation and it's purchase. If the item is checked as purchased shortly after its addition to the list, the time difference will be minimal.

Thanks for your work team :) I am happy to see this feature is almost complete ✨
You did a nice job creating the functions in dates.js and in updateItem in firebase.js.

I left a few comments, please reach out if you have any questions or need any clarifications.

This import can be deleted since not being used

Can we delete those lines?

I discovered when I create an item and mark it as purchased, the dateNextPurchased is updated to the current date:

I think this is weird bc we are rolling back the dateNextPurchase, and I believe this shouldn't be happening.
This is the item date when it was first created, before being marked as purchased:

What do you think?

Nice job ⚡️
