Why it's used

Pause between API calls to respect rate limits.

Common errors

Forgetting parentheses on sleep. Write Utilities.sleep(), not Utilities.sleep or sleep by itself.

Adding spaces where they do not belong. Write Utilities.sleep(), not Utilities .sleep(), Utilities.sleep (), or Utilities . sleep().
Wrong capitalization. Use Utilities and sleep, not utilities or sleep.
