How can I keep the original ordering of a Map?

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?

If you want to preserve the insertion order, you can check :aja’s OrdMap, which does exactly that, as well as offering good performance and implementing the Jason.Encoder protocol amongst other things:

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