如何将主Javascript文件导入其他文件？

Question

I currently have separate Javascript code for each HTML page I have. I wrote some JavaScript code that I use frequently for HTTP requests to my Node server and it's my understanding that the code would run more efficiently if I moved this code to a central file and referenced it elsewhere. How can I import this file into another? Also, will doing so result in any more efficiency or will it just look cleaner?

You can easy import file to another file in node.js , but you want to import it in front-end, so you can only include a script file in an HTML page, not in another script file. You can write JavaScript which loads your "included" script into the same page using the following:

var imported = document.createElement('script');
imported.src = '/path/to/imported/script';
document.head.appendChild(imported);
