Refactor (public/src/modules/topicList.js): reduce complexity in onTopicsLoaded

[newperson1746]

1. Issue

Please provide a link to the associated GitHub issue:

#264

Full path to the refactored file:
public/src/modules/topicList.js

What do you think this file does?
Handles client display of topics once a category is opened.

What is the scope of your refactoring within that file?
onTopicsLoaded

Which Qlty‑reported issue did you address?
High complexity 10 in onTopicsLoaded

2. Refactoring

How did the specific issue you chose impact the codebase’s adaptability?
Cluttered logic that accomplishes defined tasks that consumes vertical space on a monitor creates unreadable code that easily begins to acquire code duplication, as seen in the first few lines of the original function. Not grouping reused logic or a long sequence of operations into helper functions means code that takes longer to understand, is more difficult to analyze because logic is not named by purpose, and encourages code rot when maintainers overlook issues when the code is too strenuous to read.

What changes did you make to resolve the issue?
Moved long operation sequences that accomplish a general task into helper functions.

How do your changes improve adaptability? Did you consider alternatives?
Decrease in complexity and increase in readability means humans can much more easily work with the code since commonly reused logic or dense sequences have been abstracted away into function calls.

3. Validation

How did you trigger the refactored code path from the UI?
Open any category

Attach a screenshot of the logs and UI demonstrating the trigger.

Attach a screenshot of qlty smells --no-snippets <full/path/to/file.js> showing fewer reported issues after the changes.
