Common Script Patterns

Parse + validate + transform​

let normalize maybeText =
  match maybeText with
  | Some text -> text |> String.toLower
  | None -> ""

Map lookup with fallback​

let getOrDefault key values fallback =
  values
  |> Map.tryGet key
  |> Option.defaultValue fallback

Branch on rich outcomes​

type Outcome =
  | Accepted of string
  | Rejected of string

Model meaningful states with unions and match over them.
