[L2Ork-dev] Node.js multithreading: What are Worker threads, and why do they matter? - LogRocket Blog

[Ivica Bukvic]

Another way I'm reading this is that this may be more reminiscent of what
I've done in the 1.x branch where the console is running essentially in a
separate TK thread to ensure that it does not have any bearing on the
visual updates of the main thread. It reads from a queue which is being
populated by the main thread, so that the console has no direct impact on
the main thread. That said, this backgrounded process seems to be a bit
different than what the TK has and may need to be investigated further.

Best,

Ico
