I'm not quite sure why Guil is calling the Tick function every 100ms and then doing the extra computation of dividing the value by 1000, instead of just configuring the the setInterval() to run every 1 second (1000ms)

This is why Guil is tracking current time and previous time to make sure that timing is accurate

Full Stack JavaScript Techdegree Student 10,331 PointsThe problem is that link doesn't do a good job of explaining the problem. Without understanding it, I can only interpret "calls are throttled to a minimum of once every 4 ms" to mean there is a four second delay. This is the best explanation I could find.
The thing isβ¦ browsers donβt really respect that milliseconds thing. You see, historically, web developers have abused setTimeout. A lot. To the point where browsers have had to add mitigations for setTimeout(/* ... */, 0) to avoid locking up the browserβs main thread, because a lot of websites tended to throw around setTimeout(0) like confetti.
