Hi! I noticed bcrypt.js uses process.nextTick in node to delay the calculation.

Unfortunately, repeated calls to nextTick will still starve the event loop: https://nodejs.org/en/docs/guides/event-loop-timers-and-nexttick/#process-nexttick

nextTick is unfortunately badly named, it should've been called 'endOfThisTick`.

Can we switch to setImmediate instead?
