From here, we're going to create another function called increment time, and increment time is going to be responsible, every 500 milliseconds, for adding a new 500 milliseconds to the current time. So this will continue to accumulate half-a-seconds, kind of like a really fast clock, a clock that ticks every half a second. So we'll say, waitInterval, then we will console-log, "waiting," currentTime, divided by 1,000 seconds. Excellent, so from here, instead of using setTimeout, which is going to time out and call a function after a certain time, we're going to say setInterval. We'll pass in increment time and our…
