for index = 1, count do repeats the body with index 1 through count, including count. end closes the loop.
The loop variable is local to the loop. Use it to create each distinct label, then append that label to a result table.
objectiveLabels(count) returns Step 1 through Step count. Fix the upper bound so the last objective is present. Keep the final return shown in the starter so the checker can call or inspect your result.
Interface: objectiveLabels(count:number) -> {string}
| Input | Expected |
|---|---|
Three objectives3 | { "Step 1", "Step 2", "Step 3" } |
None0 | {} |
local labels = {}
for index = 1, 3 do
table.insert(labels, "Step " .. tostring(index))
end
return labelsThe loop appends Step 1, Step 2 and Step 3 in order.
New syntax: for index = 1, count do, end

The loop variable is local to the loop. Use it to create each distinct label, then append that label to a result table.
When count is zero, a positive-step loop from 1 to 0 has no iterations. The empty table is the useful result rather than an invented objective.
