So yeah, I don't know if you're looking for speaking tips but some things that I think would help your talk is to definitely highlight how process-based parallelism is only garbage. Processes are significant overkill for dynamically scaling a single web server and how recycling of threads is actually not garbage.
Nexus also favors idempotent and pure functions as well
It harshly punishes you for accessing globals (which is a good thing) but it should be mentioned.
You certainly won't be using threads like you would in C++ where you're having 4 threads all be part of the same array reduction
But you would be using threads to improve the performance of your web application and utilize system resources better
These are the kinds of things I think other JS developers would like to know
So, this may sound dumb, but assuming that one of my event handlers does access a reference outside of its current scope (so this means it's visible to other threads), Nexus will serialize these accesses, right?
