看了很多教程，都說process.nextTick是最先執(zhí)行的，但我自己跑的時(shí)候卻是最后執(zhí)行的。vue的nextTick按理說優(yōu)先使用promise，但我跑的時(shí)候也是比較后執(zhí)行的。watch的執(zhí)行又應(yīng)該屬于哪一種任務(wù)呢，Object.observe嗎？export default {   data() {    return {       a = false     }   }   watch: {     a() {      console.log("watch")     }   }   methods: {     myprint() {      this.a = true       setTimeout(() => console.log("settimeout"), 0)      this.$nextTick(() => console.log("vue nexttick"))       process.nextTick(() => console.log("process.nexttick"))       Promise.resolve().then(() => console.log("promise"))      console.log("start")     }   }打印出來結(jié)果為：startpromise watch vue nexttick settimeout process.nexttick
