As you can see by pasting it to geojson.io for example, one - smaller geometry is fully contained in another - bigger one.
However @turf/boolean-contains still returns false for it. Why? Or how can I implement equivalent check of whether area of smaller one fully falls under the area of bigger one - they can touch on the edges, but still.
booleanConatinsmethod requires no common boundary points: "The interiors of both geometries must intersect and, the interior and boundary of the secondary (geometry b) must not intersect the exterior of the primary (geometry a).` If you allow for common boundaries, you must usebooleanWithinmethod.
