javascript - Google maps api: what are xa and pa in get bounds?

Question

The Api reference tells me that getBounds() returns the coordinates for SW and NE extremes. When I call it, it returns me with a object with xa and pa as keys, each of them having j and k as keys where the coordinates are, seemingly randomly. I have tried to find them in the documentation but get nothing. I can write out custom code to find min and max to determine them myself, but I'm wondering if I can know what they mean.

You should use:

var bounds = map.getBounds();
var NE = bounds.getNorthEast();
var SW = bounds.getSouthWest();
