What is a common purpose of using `pause();` in Karel's programming?

Using pause(); in Karel's programming is intended to temporarily stop operations for user observation. This function serves a crucial role in allowing users to see what Karel is doing at any given moment during the program's execution. It provides an opportunity to visually confirm that Karel is performing as expected before proceeding further.

While the use of pause(); does not enhance the speed of Karel's operations nor does it reset any sensors, it is particularly useful in educational settings or debugging phases where understanding the flow of commands and their immediate effects on Karel's environment is vital. This pause allows users to take in the current state of Karel's surroundings, ensuring clarity in how commands are affecting Karel's position and actions. It also facilitates a more interactive learning experience, enabling programmers to grasp concepts in real time.
