Javascript 关于YUI压缩程序和Java脚本

我在我的网站上使用把手。因此，我需要将“handlebar.runtime.js”发送到客户端。但是我发现Offsocial网站上的“handlebar.runtime.js”没有被压缩，所以我使用YUI压缩器来压缩它

当我检查压缩的“handlebar.runtime.js”时，发生了一些奇怪的事情：与前一个代码相比，一些代码在压缩的代码中消失了。压缩的一开始是这样的：

/*!

/* exported Handlebars */
var Handlebars = (function() {
// handlebars/safe-string.js
var __module3__ = (function() {
"use strict";
var __exports__;
// Build out our basic SafeString type
function SafeString(string) {
this.string = string;
}

 SafeString.prototype.toString = function() {
  return "" + this.string;
 };

  __exports__ = SafeString;
  return __exports__;
})();

正如您所看到的，YUI压缩器并没有删除注释，代码的开头有一个奇怪的分号。有人能解释一下吗？谢谢

PS：开始未压缩的“handlebar.runtime.js”如下所示：

它仍然存在，因为起始注释

/*中有感叹号

正如使用开源库时通常所做的那样，您希望保留版权说明
，但您能否解释一下为什么一开始出现了一个奇怪的分号，并且与前一个分号相比，某些内容发生了变化？YUI compressor是否在压缩代码时更改脚本的内容？是YUI compressor优化内容以缩小文件大小。您可以使用命令行中的
--disable optimizations
选项禁用此功能。（见附件）。不完全确定额外的半专栏来自哪里，你能编辑你的帖子并添加非压缩版本的脚本吗？请看编辑后的问题，我添加了未压缩的一个开头。我找不到任何相关文档，但我猜这是一个预期行为，因此，当存在不可压缩的注释（由
/*！
定义）时，会添加半列，以防止放置在该注释之前的任何代码与注释后面的行合并。那么您的意思是分号对代码的功能没有影响？
