Consistent naming conventions are essential for code maintainability and team collaboration. In Apex, the established convention for constants is
to use SNAKE_CASE with all uppercase letters, where words are separated by underscores.
When constants don’t follow this convention, it creates several problems:
- Reduced readability: Mixed naming styles make it harder to quickly identify constants in the code
- Team confusion: Developers expect constants to follow the established pattern, and deviations can cause misunderstandings
- Maintenance overhead: Inconsistent naming makes code reviews more difficult and increases the cognitive load when working with
the codebase
The SNAKE_CASE convention for constants is widely adopted across many programming languages and is specifically recommended in Salesforce
development best practices. This convention makes constants easily distinguishable from variables and methods at a glance.
What is the potential impact?
While this issue doesn’t affect functionality, it reduces code maintainability and can slow down development. Inconsistent naming conventions make
the codebase harder to understand and maintain, especially for new team members or when working with large codebases.
