Answer 1

In the provided code, the dance function is defined once and called three times.

Here's the breakdown:

• The dance function is defined once in the code:

function dance() {
    turnLeft();
    move();
    turnLeft();
    turnLeft();
    move();
    turnLeft();
}

• The dance function is called three times within the main function:

1. The first call happens with dance(); after the first move();.
2. The second call happens with dance(); after the second move();.
3. The third call happens with another dance(); at the end of the main function.

So the answer is:

Called 3 times, defined 1 time.
