I just know that I need to use it with a requirejs, and whether I have explained the articles or books loaded on demand from the concept and principle. Please recommend to learn
I understand what you mean from the front:
The front-end js of jquery era were all introduced in html inside < script src=’xxxx.js’></script >. such a website should load all js at the beginning.
Now, if es6(react/webpack) is used, it can be introduced by import, so that a certain class will be added. I wonder if you mean that.
