main.js 코드를 다음과 같이 바꿔보세요.

import Vue from 'vue';
import TicTacToe from './TicTacToe';

new Vue(TicTacToe).$mount('#root');

위에는 선생님 깃허브에서 다운받아서 작동해봤구요... 밑에는 

this.$root.$data가 들어오지를 않습니다...

  1. {__ob__: Observer}
    1. __ob__: Observer
      1. vmCount: 1
TdComponent.vue?c5a7:15
  1. <slot style="box-sizing:border-box;min-width:0px;min-height:0px"><span class="console-object console-object-preview" tabindex="-1" style="box-sizing:border-box;min-width:0px;min-height:0px;white-space:pre-wrap;overflow-wrap:break-word;font-style:italic;word-break:break-all"><span class="object-properties-preview" style="box-sizing:border-box;min-width:0px;min-height:0px">{<span class="name" style="box-sizing:border-box;min-width:0px;min-height:0px;color:#a9a9a9;flex-shrink:0">__ob__</span>: <span class="object-value-object" style="box-sizing:border-box;min-width:0px;min-height:0px">Observer</span>}</span><span class="object-state-note info-note" style="box-sizing:border-box;min-width:0px;min-height:0px;background-color:#99aaff;display:inline-block;width:11px;height:11px;color:black;text-align:center;border-radius:3px;line-height:13px;margin:0px 6px;font-size:9px"></span></span></slot>
    1. parant: (...)

도저히 못찾겠어요.. 건너뛰어야 할까요?

1 of undefined라는데 x[1]이 있다면 x가 undefined인 것입니다. 왜 x가 undefined인지 console.log로 추적해보세요.
