Anyone who has used Java can only import the required Java classes to Java as needed.
In JavaScript, we can also implement similar functions to reduce the amount of JS files introduced and reduce network transmission.

First write an import function
Function importj (fpath ){
Fpath = fpath. Replace (/\./g, ' \ / ');
Document. Write ( ' <SCRIPT src =" ' + Basepath + Fpath +   ' . Js "> </SCRIPT> ' );
