Go provides a convenient syntax feature that allows you to group consecutive parameters of the same type together. Instead of repeating the type
for each parameter, you can omit the type from all but the last parameter in the group.
This feature serves multiple purposes:
- Reduces visual clutter: Eliminating redundant type declarations makes function signatures cleaner and easier to read.
- Follows Go idioms: The Go community and official documentation consistently use this syntax pattern, making it the expected
style.
- Improves maintainability: When you need to change the type of grouped parameters, you only need to update it in one place.
The Go language designers included this feature specifically to make code more concise while maintaining clarity. Using the grouped syntax
demonstrates familiarity with Go conventions and produces code that feels natural to other Go developers.
What is the potential impact?
This issue affects code readability and consistency. While it doesn’t impact functionality, using non-idiomatic Go syntax can make code appear less
professional and may slow down code reviews as developers notice the style inconsistency.
