Walkthrough

Three files receive null-safety improvements applying the nullish coalescing operator to properties accessed during formatting. Mileage fields in vehicle-related components and the total amount in the customer dashboard now default to zero when undefined, preventing potential runtime errors.

Changes

Cohort / File(s)	Summary
Vehicle Mileage Null-Safety src/app/components/VehicleCard.tsx, src/app/dashboard/vehicles/[vehicleId]/page.tsx	Apply nullish coalescing operator to mileage field before toLocaleString() formatting, defaulting to 0 when undefined
Invoice Amount Null-Safety src/app/components/dashboards/CustomerDashboard.tsx	Apply nullish coalescing operator to totalAmount field before toLocaleString() formatting, defaulting to 0 when undefined

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~3 minutes

• Repetitive null-coalescing operator additions across three files
• No behavioral logic changes or control flow modifications
• Straightforward defensive programming pattern applied consistently

Poem

🐰 A rabbit hops through code so bright,
Where nulls once lurked in morning's light.
With coalescing touch so fine,
Zero-defaults now align.
No crashes 'cross the dev's domain—
Safe formatting is our gain! ✨
