🛠 Console Problems Fixed in React While running the project, React was showing multiple console warnings and errors. 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. |

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
keyprop to each product item using the product'sid. This removes the console warning and ensures proper rendering behavior.No other functionality was changed.
