[Jakub Kowal]

I am getting following error:

RangeError: Maximum call stack size exceeded

When I use turf difference function between 2 polygons:

    const pol1 = [

    let polygon1 = turf.polygon(pol1);
    let polygon2 = turf.polygon(pol2);
    polygon1 = turf.difference(polygon1, polygon2);

Here is visualization of these two polygons on map:
polygon 1
polygon 2

Turf version: 6.5.0.

@KubiO24 you'll find a number of turf issues submitted with a similar error. Try running turf.truncate() on your polygons first. There's known floating point issues with the underlying polygon-clipping library. Please close the ticket if this resolves it.
