⏱️ Stopwatch

A sleek and precise stopwatch built with React.js, JavaScript, and TailwindCSS. Designed for high-resolution time tracking, this tool features start, reset, and resume controls—perfect for productivity, sports, or experimental timing.

🎯 Challenge Overview

🕒 Estimated Completion Time: 30–45 minutes

🛠️ Task Overview:

Build a stopwatch that tracks time down to hundredths of a second. Users should be able to start, pause, resume, and reset the timer with intuitive controls and a visually engaging circular dial.

📌 Requirements:

  • ▶️ Start Button: Begins time tracking.
  • ⏸️ Pause/Resume Button: Allows pausing and resuming the stopwatch.
  • 🔄 Reset Button: Resets the timer to 00:00:00.
  • 🧭 Time Display: Shows elapsed time in MM:SS:HS format (hundredths of a second).
  • ⚛️ State Management: Use React hooks to manage timer state and intervals.
  • 🎨 Styling: Circular dial layout with modern dark theme using TailwindCSS.

🔍 Development Focus:

  • Component Modularity → Reusable Timer, Dial, and Control components.
  • UX Clarity → Smooth transitions, clear button states, and responsive layout.
  • Performance → Accurate interval handling with cleanup logic.
  • Accessibility → Keyboard-friendly controls and semantic HTML.

🌟 Additional Considerations:

  • Add lap tracking or split time functionality.
  • Consider sound or haptic feedback on control actions.
  • Expand to include countdown mode or exportable logs.
