Techniques and Tools for Taming Tangled Twisted Trains of Thought
summary
Node is single threaded and nonblocking so the concrete claims are: callbacks are the scheduling primitive, wrapping low-level ops yields simpler APIs (an explicit fs.readFile wrapper that opens reads loops and closes), parallel waiting needs explicit callback counters to know when all callbacks finish, and event emitters handle repeated events. Libraries shown include the step library for serial and parallel flow and promised-io for promises. CPU-bound work blocks the whole server and blocking native libraries must be avoided.
