推荐答案

Well的性能形式，这取决于JS代码的数量.

一般而言:
通过编写单独的JavaScript文件并包含.js文件
此选项将使您获得良好的性能，因为它是一个外部文件，一旦下载到客户端，就可以缓存并多次使用.会减少响应的大小和时间.
这种方法还有助于维护性和部署/交付.


如果您的JS代码非常小，几乎没有警报，那么也可以内联完成.

Well, it would depend on amount of JS code.

In general:
by writing separate JavaScript file and by including .js file
This option would let you to a good performance as it would be an external file which once downloaded on client can be cached and used multiple times. Would reduce the response size and time.
This approach also helps in maintainability and deployment/delivery.


If you have very small JS code, kind of few alerts or so then it can also be done inline.
