```js { tag: 'DIV', attrs:{ id:'app' }, children: [ { tag: 'SPAN', children: [ { tag: 'A', children: [] } ] }, { tag: 'SPAN', children: [ { tag: 'A', children: [] }, { tag: 'A', children: [] } ] } ] } 把上诉虚拟Dom转化成下方真实Dom <div id="app"> <span> <a></a> </span> <span> <a></a> <a></a> </span> </div> ```
