Function

findFirstLevel

findFirstLevel<Item extends { standing: CourseStanding }>(
items: readonly Item[],
): Item & { standing: LevelStanding } | undefined
Finds "the first course": the item standing at level 1.
Type Parameters
- Item extends { standing: CourseStanding }
Parameters
- items: readonly Item[]
  Anything carrying a CourseStanding
Returns Item & { standing: LevelStanding } | undefined
The level-1 item, or undefined when the catalog holds no level

Remarks
Every surface that names or starts the first course goes through here, so a reference course can never take that place, whatever its sequence.
