res [terminology]

Terminology¶

Use for a return collection or constructed output.
Typical types include:
- Lists
- Nested lists
- Sets
- Mappings
- Constructed strings
It is most suitable when the function is short and the output's meaning is obvious from the function.
Prefer a semantic name such as colors or dist when it conveys important structure.
