NodeJS eventEmitter回调函数内如何突破自触发次数限制

Question

const EventEmitter = require('events')class MyEmitter extends EventEmitter {}const myEmitter = new MyEmitter()let times = 0myEmitter.on('canReceive', function () {    console.log(++times)    myEmitter.emit('canReceive')})myEmitter.emit('canReceive')为何栈溢出了，有什么方式可以一直触发但是防止溢出吗？

Answer 1

给他一点时间

myEmitter.on('canReceive', function () {

    console.log(++times)

    setTimeout(function () => {

        myEmitter.emit('canReceive')

    }, 0)

})

Answer 2

on...本来就是等待触发时机的~
