Write a JavaScript function formatCountdown(gameDate) that returns a friendly string like ‘Live now’, ‘Tonight 7:30 PM’, ‘Tomorrow 8:20 PM’, ‘in 3 days’, or ‘Sat, Oct 17 · 3:30 PM’ in Eastern time. Include a few test cases.

How the agent did it
- Built Game Day Glance using Cursor with Grok to show upcoming Atlanta team games.
- Adjusted the app so live games appeared at the top.
- Submitted the same countdown-function prompt to three models in Cursor.
During Global Hack Week, the author built Game Day Glance, an app showing when their favorite Atlanta sports teams play next. They used Cursor with Grok and report that the first generated version already had satisfactory colors and layout. The one change they describe was moving live games to the top so ongoing action could be followed in one place.
The author liked the app's refresh button, although they found initial generation slow. They supplied a live app link in the recap. They then used a real function from the project as a separate model comparison task inside Cursor: formatting game countdowns in Eastern time.
The same prompt went to Grok 4.7, Claude Opus 5.5 and Gemini Flash 3.8, asking for a JavaScript function and test cases. The author reports that all three produced working functions. Grok was the slowest, Claude was fast, and Gemini fell between them while providing the most test cases and showing code snippets alongside files.
This account combines a small app build, a targeted presentation change and a comparison based on code the app actually needed.
