Top React countdown component libraries

Building your own countdown timer using React Hook

To create a countdown timer from scratch using React Hook, you can start with a simple version that tracks the timer interval without causing re-renders. However, for a more robust countdown timer, consider factors like tracking actual time between ticks, allowing users to pause and resume the timer, providing callbacks for time changes, and ensuring no leftover intervals for memory leaks.
