expression (i + 1) % pointsCount is used for getting the next vertex coordinates, the area value could be either positive or negative depending on the coordinates but Math.abs(area) returns the absolute value

are google.maps.geometry.spherical.computeArea() with computeArea() used same formula? if it use different formula, what the different both of them?
