Value created with new.

Area 2, Values and types; not declinable; the next step is usually the agent's.

A value is made with Type(value), or an object with Type { field: value }, without new.

example

type CustomerNote = Text {    max_length: 500}type NoteWasEdited = Bool {}function edited(before: CustomerNote, after: CustomerNote) -> NoteWasEdited {    return new NoteWasEdited(before != after)}

  |8 |     return new NoteWasEdited(before != after)  |            ^^^ remove `new`

reason: new creates an object in JavaScript, TypeScript, Java and C#; Jadpo creates a value with Type(value), or an object with Type { field: value }.
next: Remove new (agent)
