#settimeout

Non‑deterministic execution order of setImmediate() and setTimeout(0) in top‑level Node.js scripts

Determine whether Node.js guarantees that setImmediate() callbacks run before setTimeout(fn,0) when both are scheduled from the synchronous top‑level scope, outside any I/O phase. The event‑loop specification defines the check and timer phases but does not fix their relative priority for callbacks queued in the main module, and recursive process.nextTick() c
