Program breaks if 'callback' takes more time than 'dalay' in setInterval

[notadilnaqvi]

setInterval(callback, delay) runs after delay milliseconds. If the callback takes more time to run than these delay milliseonds (because of slower API/database responses), the program will break.

In context of this program, it only takes about 15 seconds for the async callback to run once. The delay is set to 2 minutes to avoid said problem. This 2-minute delay gives callback plenty of time to finish. But this is not efficient as the program is sitting idle rest of the time.

A probable solution is to use the equivalent of a sleep function in Python details of which can be found here.
