Why get() does not take 0 parameters in JavaScript ProcessingJS?

 

According to the ProcessingJS documentation, get(); should return an image of the entire canvas.

On Khan Academy, get(); returns OhNoes with a confusing error message, saying that get takes 2, 3, 4 or 5 parameters.

 

Workaround

get(0, 0, width, height); returns an image of the entire canvas.

Note: This article is based on a discussion about the get(); function found here in the Help Center. The discussion also demonstrates an example where the get() method does take 0 parameters as expected.

Exception: A user created PGraphics object permits executing the get() method directly on that object with no arguments.
