Return {hasPass=false, visits=0, nickname="", sponsorType="nil"}. The empty nickname and zero visits are real values; only sponsor is absent.
Interface: Return a table with enabledType, brightnessType, labelType, ownerType.
| Input | Expected |
|---|---|
Empty but present values | { hasPass = false, visits = 0, nickname = "", sponsorType = "nil" } |
local enabled = false
local owner
print(type(enabled))
print(type(owner))
return { enabledType = type(enabled), ownerType = type(owner) }A deliberate false remains boolean. The unassigned owner is nil. Neither should be silently replaced by the text "false".
New syntax: nil, type()
true and false are booleans. nil means no value; a local declared without an assignment starts as nil. type reports a basic language type as text.
The text "false" is a string and the number 0 is a number. Neither is the boolean false. Quotes change meaning.
A table groups named results here so the checker can inspect all four labels. Dictionary tables are explored fully in Chapter 4. Read each key as a label for its result.
