What function is used to toggle visibility of a shape in CodeHS?

The function that is used to toggle the visibility of a shape in CodeHS is setVisible(true or false). This function allows you to control whether a shape is displayed on the screen. When you pass true as an argument, the shape becomes visible, and when you pass false, the shape is hidden. This provides a straightforward way to manage the appearance of shapes in your animations or games, allowing for dynamic changes during the execution of your program.

The other options do not represent the correct syntax or function used for toggling visibility in CodeHS, which is why they are not applicable. Each of those alternatives may imply some form of visibility control, but they utilize incorrect function names or parameters that do not align with the CodeHS standard library for shapes.
