For multi-geometries, it sums the lengths of individual components. The method accepts `maxError` to define reprojection tolerance and `proj` to specify output units (defaults to meters). Applying it to a point will return a float. Example codes are provided in both JavaScript and Python to define a point object, calculate its length, and display it on a map.\n"]]
