reactionTimer2026

You need to develop a reaction timer app to test reaction times and record the fastest. You will need a server that serves up a web page. Think through how the timer is "fair". Consider how to deal with someone who rapidly keeps clicking, or uses some other mechanism to "cheat" your system.

Run the app

1. Open public/index.html in your browser.

Notes

• The random wait is between 2 and 10 seconds.
• Only the first click after the STOP sign counts.
• False starts reset the round and show a warning.
• The leaderboard keeps the fastest five times for the current session.
