👉 The commented engineering in the provided code snippet is a form of inline documentation that offers developers insight into specific lines or blocks of code without altering their functionality. These comments are typically placed directly above or next to the lines they describe, often in a developer's IDE or text editor. They serve multiple purposes: they clarify the intent behind complex logic, explain non-obvious design decisions, document parameters and return values of functions, and highlight edge cases or potential pitfalls. This form of documentation is crucial for maintaining code readability, especially in larger projects where understanding the rationale behind certain implementations is essential for future maintenance and collaboration. By providing context, these comments help new developers quickly grasp the code's purpose and functionality, while experienced engineers can easily reference them for quick troubleshooting or to understand the reasoning behind specific design choices.
