When it comes to code readability and understanding, a well-documented and organized codebase is key.
Here's a checklist to ensure your code is easier to comprehend for both yourself and others.
Information and Comments:
- Comments should always provide value, adding insights and explanations to the code.
- In-line comments are helpful to explain the purpose and intention, especially for junior developers.
Top Comment Block:
- Clearly describe what the code does and its business purpose.
- If the code has been modified, explain the reason behind the modifications.
- Include feature/story reference numbers, original as well as modifications.
- Mention the date the class was last modified.
- Identify any related classes, flows.
- Provide the name of the developer who last modified the code.
In-Line Comments:
- Above variables, explain their purpose and usage.
- Above SOQL queries, describe why the query is needed.
- Above loops, clarify the purpose and reason behind the loop.
- Above DML statements, explain what is being committed and why.
- Above catch blocks, detail what is being handled in the exception.
- Above any limit checks, specify the limits being checked and why.
Additional Suggestions:
- Use descriptive variable and method names for better code readability.
- Break down complex sections into smaller, manageable functions.
- Utilize consistent indentations and spacing for improved code organization.
- Keep comments up to date and relevant.
- Maintain a consistent coding style for easier collaboration with other developers.
- Consider unit testing to validate your functionality.
Remember, well-documented code leads to faster comprehension, higher collaboration, and smoother development.
