Variance from budget
A ledger compares what was planned against what actually happened: report the signed difference.
- Variance is actual minus budget.
- The result keeps its sign — overspend is positive, underspend negative.
budgetVariance(budget: int, actual: int) → int
Where you start
function budgetVariance(budget: number, actual: number): number {
