Remove difference between two Geojson layers using Turfjs

I’ve draw line programmatically (not using leaflet draw) inside polygone using leaflet draw plugin on map, I want to keep only the points of polyline that are inside of polygone and remove those are outside. Using difference method of Turfsjs library, I can get the “difference” layer between the polygon and line, now I want to remove the difference between this layers from map and keep only the polygone and part of line that is inside the polygon. Any help is much appreciated. Thank you. Here is a code snippet:

var line = path.toGeoJSON();
var polygon = selectedPoly.toGeoJSON();
var difference
var result = []
var difference = turf.difference(line, polygon)
var if (difference) {
  result.push(difference)
  var inter = L.geoJson(result).addTo(map);
}

Here is a screenshot of difference method :

This is what I want to get:

Hi @marie15 - turf will not do things like remove the old parts of the polygon from the map, turf does not tied to any particular mapping library (eg leaflet or open layers) etc, it only concerns itself with spatial operations on geojson.

As suggested above a jsfiddle might help us give you the best assistance.
