Question

Can you please elaborate? Say I'm running a server on NodeJS. A

user has a balance of 10 dollars.
What if they send 2 requests to withdraw their balance at the same time?
As the server would process 2 requests, it would see the balance to be 10$ at the time of each request, right?
So it would allow both requests to go through and append 2 records, making the balance -10$

You will have to determine an order to those requests and execute them one after the other in isolation. Meaning in your case, one of the requests must fail
