javascript - 如何在 JavaScript 中删除撇号？

Question

这是针对预科课程 Thinkful 的挑战之一，所以这实际上不是一个问题，我可能会因为作弊或类似的事情而遇到麻烦，但我粘贴了问题和期望结果如下的代码哦，我只是无法做到这一点，我已经尝试了一切。

Diego 有两首歌曲的歌词，他想在他的网站上显示。第一个是“见一千件事”，另一个是“我们都是光”。歌曲标题以小写文本且没有标点符号存储在数据库中，因此要找到正确的歌词，我们需要转换 songTitle 变量以匹配存储在数据库中的内容。你能用你对字符串方法的知识来：1）小写songTitle变量和2）从songTitle中删除所有撇号吗？

以下是我尝试过的方法：

songTitle.replace("[\s']","","ALL"); (failed), 
songTitle.replace(/[']+/g,""));
