What I Tested

I wrote solitary and sociable tests for formatDateTime in utils/format-date-time.test.ts, covering: option-passing behavior (mocked toLocaleDateString), default/explicit includeTime: true, includeTime: false (year instead of time), and invalid/empty/null/undefined date string handling.

Potential Bugs Found

Two bugs found in utils/format-date-time.ts, both fixed in the implementation:

1. Only the first comma was stripped from the formatted string. .replace(",", "") was changed to .replace(/,/g, "") to remove all commas. Without this, dates like "Sat, Mar 23, 2024" would produce "Sat Mar 23, 2024" instead of "Sat Mar 23 2024".

2. null and undefined inputs were passed to new Date(), which produces the epoch date (Jan 1, 1970) rather than "Invalid Date". A guard clause if (!dateString) return "Invalid Date" was added before the Date constructor call.

Non-Code Tasks

None.
