External Documentation vs Inline Comments

Developers should learn and use external documentation to improve software usability, maintainability, and collaboration, especially in team environments or for public-facing projects meets developers should use inline comments to explain non-obvious code behavior, document workarounds or temporary fixes, and provide context for complex algorithms or business logic, especially in collaborative projects or legacy systems. Here's our take.

External Documentation

Nice Pick

Developers should learn and use external documentation to improve software usability, maintainability, and collaboration, especially in team environments or for public-facing projects

Pros

• It is essential when building APIs, libraries, or complex systems where users need clear instructions beyond code, such as in open-source contributions, enterprise software, or regulatory compliance scenarios
• Related to: technical-writing, api-documentation

Cons

• Specific tradeoffs depend on your use case

Inline Comments

Developers should use inline comments to explain non-obvious code behavior, document workarounds or temporary fixes, and provide context for complex algorithms or business logic, especially in collaborative projects or legacy systems

Pros

• They are essential for onboarding new team members, debugging, and ensuring code sustainability, but should be used judiciously to avoid clutter and redundancy with self-documenting code
• Related to: code-documentation, clean-code

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. External Documentation is a methodology while Inline Comments is a concept. We picked External Documentation based on overall popularity, but your choice depends on what you're building.

The Bottom Line

External Documentation wins

Based on overall popularity. External Documentation is more widely used, but Inline Comments excels in its own space.
