The code you've shown is atomic (it will completely finish before another event handler can run), so you shouldn't have any synchronization issues. Remember that in node, all user-written code runs in a single thread. If somebody else is trying to connect, it won't interrupt what you're doing.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
