Fix unique key console warning in CartItems

[dipesh-y]

Problem

React was showing a console warning about unique keys in the CartItems component when rendering a list of products. Without unique keys, React cannot efficiently track list items during re-rendering.

Solution

Added a unique key prop to each product item using the product's id. This removes the console warning and ensures proper rendering behavior.

No other functionality was changed.

🛠 Console Problems Fixed in React

While running the project, React was showing multiple console warnings and errors.
This usually happens when:

Both frontend (React) and backend (API server) are running in the same terminal session,

Or when dependencies/scripts conflict.

✅ Fix Applied:

I used separate terminals to run the project:

One terminal for frontend → npm start (React app)

Another terminal for backend → nodemon index.js(or your API start command)

This separation avoids overlapping logs, makes debugging easier, and stops React from spamming the console with unnecessary warnings.
