I found this during code review...
During a recent code review, I encountered a perplexing situation. The codebase in question had an excessive number of nested div
elements, resulting in a highly convoluted structure. It was clear that whoever wrote this code didn't adhere to best practices for React development. Let's delve into what made this code particularly troublesome.
The nested structure's complexity seems unnecessary, with multiple div
elements labeled numerically (e.g., div 12, div 9, div 10) without a clear hierarchical or functional purpose. Each div
was styled using some form of a style component, which in itself isn’t problematic. However, the sheer number of nested div
elements complicates both the code readability and maintainability.
Issues Observed
- Excessive Divs: There were numerous nested
div
elements, something not typically seen in well-structured React code. - Naming Conventions: The numeric naming of
div
elements is confusing and makes it difficult to understand the page's structure or functionality. - Code Maintainability: Adding new features or debugging issues becomes nearly impossible due to the overly complicated nested structure.
Recommendations
This example is an epitome of what not to do in React coding. From my experience, if I had to review this piece of code, my recommendation would be straightforward: this page needs to be completely rewritten. Instead of attempting to refactor such a convoluted structure, starting from scratch would be more efficient.
If I needed to make any modifications or additions to this page, I wouldn’t even know where to begin. Would I insert the new component into div nine
, div 10
, or perhaps Flex one diff two
? The complexity is unwarranted and burdensome.
Conclusion
This is definitely not how React was meant to be used. When structuring components in a React application, it is crucial to follow best practices that maintain code readability, scalability, and maintainability. From this example, it's evident that adhering to these principles is essential to avoid such convoluted and unwieldy structures.

FAQ
Q: What was the main issue observed in the React code?
A: The main issue was the excessive number of nested div
elements, which made the code extremely convoluted and difficult to maintain.
Q: Why is having too many nested div
elements problematic?
A: It complicates the code structure, making it difficult to read, understand, and maintain over time. Additionally, it can create challenges when modifications or debugging are needed.
Q: What recommendation was given for handling such a codebase?
A: The recommendation is to kill the existing page and start over, as attempting to refactor such a complex and unwieldy structure would be impractical.
Q: How does naming convention impact code readability?
A: Poor naming conventions, such as numerically labeling div
elements, obscure the purpose and hierarchy of the code, making it hard for developers to navigate and understand.
Q: What best practices should be followed when working with React?
A: Follow a clear and logical component structure, use meaningful names for elements, maintain simplicity, and aim for code readability and ease of maintenance.
