Functionalities of Timer Component

  • Elapsed Time Display: Upon mounting, the Timer Component will display the elapsed time in hours, minutes, and seconds.
  • Countdown Timer: Users can set custom countdown durations according to their requirements.
  • Dynamic Timer Updates: Leveraging the useEffect hook, the Timer Component will update in real-time, reflecting changes in countdown duration and elapsed time.
  • Timer Controls: Users will have control over the timer through intuitive buttons, enabling them to start, pause, reset, and edit the countdown duration seamlessly.

Creating a Timer Component with useEffect Hook in React

Timer Component using React along with its useEffect hook will not only display the elapsed time since the component mounts but also allow users to set and manage the countdown timer dynamically.
