Javascript namespace to improve code reusability _ javascript skills

Add namespaces to your encapsulated javascript library to improve code reusability. After more than 10 js files are introduced to the same web page,
Functions with the same name in each js are prone to conflicts.
For example, the addCssStyle method is written in the xxx library,
The yyy Library also writes an addCssStyle method,
The specific implementation of these two methods is different.
When these two components are referenced at the same time, the page effect changes after a function conflict occurs,
Debugging and modification are both very painful. To avoid conflicts,
It is even more depressing to give up Referencing some excellent components.

Therefore, when encapsulating javascript Component Libraries, use namespaces to avoid conflicts.
All methods and variables must be written according to the class name of the package name.
(Writing code is as convenient as encapsulating java's util method)
As a result, my js library is encapsulated as follows.
After google for half a day, there was no ready-made product, so I found out it myself. The sample code is as follows:
