Insufficient Code Commenting and Documentation in campaigns.js

[BrosG]

The code would benefit from more comments explaining what specific blocks of code or functions are doing. This is especially true for the more complex sections of the code.

Impact: Without adequate comments and documentation, it can be difficult for other developers (or even the same developer at a later date) to understand what the code is supposed to do, leading to a higher risk of bugs when changes are made.

Suggested Fix: Add comments to explain the purpose and functionality of complex or non-obvious sections of code. In addition, consider adding more comprehensive documentation at the top of the file or function definitions.
