I will share with you some experiences on restructuring the JS front-end framework. If you are interested, don't miss it. After all, it's an experience. Let's get started. Refactoring is actually not a major action. The main function to be implemented is to re-divide the existing JS Code and decouple the existing modules. Then I plan to divide the existing program into modules and repackage it into a namespace to implement use or something similar to java Package. So I only need to load a js fil
