Hey everyone!
How can I keep the original ordering of a Map?
I’ve created one and notice that after the creation, the order of elements altered in alfabetically. How can I keep them?

You need to create your own struct and implement that on your own.

Then don’t use a map but a keyword list instead. Elixir’s stdlib supports it well, check the
Listmodule in the docs.cmo
If it’s just for your own pleasure in dev or when debugging,
IO.inspectanddbgtake options to allow thiscustom_options: [sort_maps: true]. I feel likepretty: truemight do as well.sabiwara
If you want to preserve the insertion order, you can check
:aja’sOrdMap, which does exactly that, as well as offering good performance and implementing theJason.Encoderprotocol amongst other things:(disclaimer: I’m the author
