一段混淆过的 JavaScript 代码，不使用浏览器的情况下该如何得到他的运行结果？

已知信息是，运行会得到一个图片链接和三个视频链接，图片链接为https://lh4.googleusercontent.com/g05HOe8CBdBal504UtHa31cCkMgEZh7Y7FEZp8ga9OQLGd5hMfzGPg=w480-h270-n，视频链接分别为 link1, link2 和 link3。（因为太长所以放在链接里了）

除了用浏览器, 还可以用 NodeJS, 或者 WScript 或者 CScript 来运行这段代码.

去掉代码中的 <script> 标签, 然后把 eval 去掉, 前面改成赋值语句, 最终输出这个变量的值就可以了.

nodejs 可以用 console.log 来输出, WScript/CScript 用 WScript.Echo 来输出.
运行结果如下:

还原后的代码:
