What are the small circled numbers to the left of what the console is logging?

It's usually a 2, sometimes a 3. Even though there are supposed to be 10 different random numbers logged to the console, sometimes there are only 8 or 9, with some numbers having a circled 2 to their left. At first I assumed it was grouping the numbers that appeared multiple times, but there are other numbers that appear multiple times and don't get combined as such. What's going on here, and what's causing it?

It sounds to me like what you are seeing is:

  • the console has printed the same output more than once in a row
  • instead of displaying the same output twice, the console only shows it once
  • but it includes a number next to the line of output indicating how many times that line has been repeated.
