Thanks for the video now I got the clarity on race conditions.

What's the remedy to the situation?

[@DevSecHacker]

we need to implement proper synchronization mechanisms to ensure the correct and secure execution of code in multi-threaded or concurrent environments.
For achieving it
1. we need to implement atomic operations designed to be executed as a single, uninterruptible unit, preventing race conditions.
2. locking mechanisms which Locks ensure that only one thread can access a shared resource at a time.
In our case, findOneAndUpdate mongo query will help to prevent this.
