Example of using partial application as a way to solve side loaded JSON with immutable value objects

Decoding.swift

// Returning a function here, instead of a fully realized object

extension Company: Decodable {
  static func decode(j: JSON) -> Decoded<[People] -> Company> {
    return create
      <^> j <| "id"
      <*> j <| ["attributes", "name"]
  }
}

func parse(j: JSON) -> Company? {
  // "included" holds the related people for the company
  let company = (j <| "data" >>- Company.decode) <*> j <|| "included"
  return company.value
}
