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 = 0

myEmitter.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~
