Proper Handling of Set Intervals in Browser Development

To ensure accurate time calculations in the browser, it is crucial to use timestamps to track start time and continuously compute time differences in each loop. Set intervals may not run at precise intervals due to background processes like switching apps or tab snoozing.

The function scheduled by set interval is placed at the end of the event loop queue, which may be delayed if preceding tasks are resource-intensive.
