I’m currently working through the book Programming Elm by Jeremy Fairbank. I’m on Chapter 4, where he introduces JSON decoders and the Json.Decode.Pipeline
package. Please bear with me, as I’m an Elm beginner. I’m also working in the Elm repl, as I’m not currently sure how to translate my work into a full Elm program.
In Elm, the order of required
s in a JSON decode pipeline shouldn’t matter for successful decoding, because we’re matching the names of the keys in the JSON oject to the names of the fields in a record. There is no inherent order to the fields of an Elm record, just as there is no inherent order to the properties of a JSON object.
