原生JS实现点击数字小游戏，供大家参考，具体内容如下
最近公司在季度测试中出了一道很有趣的测试题，要求使用我们自己的黑科技–IVX来实现,感兴趣的朋友可以去了解哦，是真的黑科技，在这里我还是用原生JS来实现吧，题目是这样的：
实现一个点击数字的小游戏：依次点击容器中随机生成的数字元素，生成的数字元素会在5S后消失，你将凭借记忆点击按照数字升序依次点击生成的数字方可通过该关卡游戏。
话不多说直接看运行效果图：
上代码：

<h1>点击数字小游戏</h1>
<p>
5s后数字内容会消失，凭借你的记忆按照数字升序依次点击数字点可顺利通关

<button

>
停止计时
</button>
<p>时间</p>

至此一个很有趣的锻炼大脑逻辑的小游戏分享完毕。
