| 2024-10-02 15:58:43 +0200 | <lortabac> | but since 'fetchUserByID' is an IO action you need (traverse fetchUserByID userIds) |
| 2024-10-02 15:57:50 +0200 | <lortabac> | if it was a pure computation you would do (map fetchUserByID userIds) |
| 2024-10-02 15:57:20 +0200 | <lortabac> | immagine you have a list of user ID's and want to fetch the corrisponding users from the database |

| 2024-10-02 15:54:54 +0200 | <lortabac> | __monty__: you can think of 'traverse' as an 'fmap' in which the function is not pure but includes an Applicative "effect" |

| 2024-10-02 15:49:14 +0200 | <Rembane> | But in a handwavy way: it's fmap and then sequence because I need to change swap f and t |

| 2024-10-02 15:36:10 +0200 | <__monty__> | Anyone have a good mental model of what "traverse" does? I think my difficulties with <*> are leaking into my lack of understanding of Traversable. |
