Coding problem1

1. Design Question

They told me to Use crud operation handling all edge cases I have to store retrieve data manipulate and show to the users so (I cannot disclose the exact question) So you have to build logic to manipulate data according to the question and give back the result. Lastly, you have to upload it on the server to make it live.

Problem approach

Tip 1 : Just go well with node js making routes for each operation with the handling of edge cases
Tip 2 : Know about MongoDB to retrieve data
Tip 3 : Deploy on the server, I personally use netifly for the frontend and Heroku for the backend
