Why does the order of required statements matter in a JSON Decode Pipeline?

Background

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.

What I Expect to Happen

In Elm, the order of requireds 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.

Course Learning Objectives

Modeling begins before you ever touch a computer

• How do I understand the system of interest?
• Within that system, what phenomena am I interested in?
• What entities do I think are relevant for my model?
• How might I qualitatively describe entity relationships in the model? (Example: predators hunt prey, so predators should have some contribution to the reduction of prey.)
• What simplifications do I know I’m making?
• How can I express expectations of/predictions about the model? (E.g., with one wolf and 10 million rabbits, I don’t think there will be much of a predator effect. Or: here’s a sketch of the path I think this orbiting body might take. Or: based on my experiences with kerbal space program, I figure the object would take a path like this.)

• Be Present
• Be Kind
• Take Space and Make Space (be mindful of how much time/space you're taking up and be willing to yield to others)
• For morning review, put your questions up the night before
• Listen without interrupting
• It's ok to talk about friction we might have working with each other
• Confirming that we understand each other by rephrasing. ("What I'm hearing is...")
• No Question Is a Ridiculous Question
• Every mistake can teach you something. Treat mistakes as growth and learning opportunities.
• This is also true of unintenionally harmful communication

Engineering Ethics and Workplace Norms(?)

What do you hope to get out of this?

• Hear Brian call 1902GH his favorite cohort
• What are bad ethics? Why do we we even need to know engineering ethics?
• How Facebook got to where it was?
  • How do we prevent those kinds of things from happening?
  • How do we see it in a work?
  • What is our role as engineers in a company when it comes to that?
