What are some common code smells that indicate a need for refactoring in OutSystems?

The presence of duplicate code, long methods, large modules, high coupling, low cohesion, and commented-out code signifies various challenges related to code quality and maintainability in OutSystems applications. These code smells are critical indicators that can hinder the readability, flexibility, and overall performance of the codebase.

Duplicate code can lead to increased difficulties in maintaining and updating the system, as changes need to be made in multiple places. Long methods often indicate the need for breaking down tasks into smaller, more manageable pieces, which not only improves clarity but also allows for easier testing and reusability. Large modules can complicate the understanding of functionality, while high coupling makes it difficult to isolate components for changes, leading to increased risk of introducing bugs. Low cohesion suggests that the module is trying to accomplish too many unrelated tasks, which can confuse developers and reduce the effectiveness of the codebase. Finally, commented-out code is a sign that there may be unnecessary remnants of old functionality, indicating a lack of clarity about what parts of the code are still relevant.

Addressing these smells through refactoring can significantly enhance code quality and maintainability, ensuring that the application can evolve more efficiently over time.
