How to know the direction of the countdown timer?

Question

JavaScript

Tell me pliz how to find out the direction of the countdown timer?
There is a function that, using setInterval , runs every 5 seconds and cycles through the array, each processed object has a timer for 30 minutes, but the catch is that in some objects the timer starts from 0 and counts up to 30 minutes, and in some it’s vice versa , the countdown goes from 30 to 0.
There are no distinctive elements in the structure.
How can you determine in which direction the timer is counting down and, for example, catch it at 20 minutes and output it to the console?

Answer 1

No code needed.
Wait and see, the number has decreased - countdown,
increased - direct.
