Deciphering a 10-digit timestamp can be perplexing. Encountered this value in a JSON API response instead of the expected date format. Initially puzzled on how to convert it for UI display, I later discovered that these 10-digit timestamps represent seconds.
Enough with the history lesson, now, how can we make it useful in JavaScript?
