nextTick 是否意味着 Node.js(事件循环)的下一阶段? [英] Does nextTick means next phase in Node.js (Event Loop)?

问题描述

process.nextTick 到底是什么意思?

nextTick 是否意味着，在当前阶段的一个元素的回调队列弹出后?或者在执行当前阶段队列中的所有回调之后进入下一阶段之前?

Does nextTick mean, after callback queue pop for one element in the current phase ? Or before moving to the next phase after executing all callbacks in the current phase's queue ?

推荐答案

这在 the文档.

nextTick 将要在当前刻度结束时调用的回调排队.整个队列在移动到下一个滴答之前被清空.

nextTick queues callbacks to be invoked at the end of the current tick. The entire queue is emptied before moving to the next tick.

与 setImmediate 对比，后者将回调排队到在下一个勾号期间调用.

(是的，名称具有误导性，但它们的行为是为了保持兼容性.)

(Yes, the names are misleading, but their behavior is that way to keep compatibility.)
