Hi Juan! My initial gut feeling is that this approach does not scale. What if you want to delete a key conditionally? Should we have delete_if?
It feels a more general approach would be to introduce `then_if`: then_if(subject, condition?, function) Or similar. :) *José Valimhttps://dashbit.co/ <https://dashbit.co/>* On Fri, Dec 6, 2024 at 3:27 PM Juan Manuel Azambuja <j...@mimiquate.com> wrote: > Hello, > > After working with Elixir for some time I have found myself repeating some > patterns when dealing with maps. > > One pattern I see repeated constantly in different apps developed by > myself or others is adding values to a map conditionally or returning the > map unchanged.
