Question

我在我的网站上使用了把手。所以我需要发送＆＃39; handlebars.runtime.js＆＃39;到客户端。但是我发现了＆＃39; handlebars.runtime.js＆＃39;来自社交网站的压缩，所以我使用YUI压缩器来压缩它。

当我检查压缩的＆＃39; handlebars.runtime.js时出现了一些奇怪的事情：当我与前一个相比时，一些代码在压缩的代码中消失了。压缩的一开始是这样的：

/*!

;var Handlebars=(function(){v (rest of the codes...)

正如您所看到的，YUI压缩器不会删除注释，并且在代码的最开头有一个奇怪的分号。有谁能解释一下？谢谢！

PS：开始未压缩的＆＃39; handlebars.runtime.js＆＃39;是这样的：
