Extract the coordinates from a GeoJSON file that displays point on my Map in OpenLayers 4

Question

Well I have this GeoJSON file :

{"type": "FeatureCollection", "features": [{"id": "1", "type": "Feature", "geometry":{"type":"Point","coordinates":[-5.8039556,35.7903036]},"properties": {"gid":"1","name":"Tanger Ville","link":"C:\\xampp\\htdocs\\final4\\img","layer":"Points"}}, {"id": "2", "type": "Feature", "geometry":{"type":"Point","coordinates":[-5.8053745,35.7896316]},"properties": {"gid":"2","name":null,"link":"C:\\xampp\\htdocs\\final4\\img","layer":"Points"}}, {"id": "3", "type": "Feature", "geometry":{"type":"Point","coordinates":[-5.8035001,35.7894603]},"properties": {"gid":"3","name":"Tanger Ville","link":"C:\\xampp\\htdocs\\final4\\img","layer":"Points"}}, {"id": "4", "type": "Feature", "geometry":{"type":"Point","coordinates":[-5.8026494,35.7909747]},"properties": {"gid":"4","name":"Tanger Ville","link":"C:\\xampp\\htdocs\\final4\\img","layer":"Points"}}, {"id": "6", "type": "Feature", "geometry":{"type":"Point","coordinates":[-5.8000892,35.7912068]},"properties": {"gid":"6","name":"Tanger Ville","link":"C:\\xampp\\htdocs\\final4\\img","layer":"Points"}}, {"id": "5", "type": "Feature", "geometry":{"type":"Point","coordinates":[-5.8034242,35.7892276]},"properties": {"gid":"5","name":"Tanger Ville","link":"C:\\xampp\\htdocs\\final4\\img","layer":"Points"}}, {"id": "7", "type": "Feature", "geometry":{"type":"Point","coordinates":[-5.8055798,35.7912481]},"properties": {"gid":"7","name":null,"link":"C:\\xampp\\htdocs\\final4\\img","layer":"Points"}}, {"id": "8", "type": "Feature", "geometry":{"type":"Point","coordinates":[-5.8046302,35.7890426]},"properties": {"gid":"8","name":null,"link":"C:\\xampp\\htdocs\\final4\\img","layer":"Points"}}]}

I want to retrieve only the coordinates , I used this function but It didn't work

var features = point_layer.getSource().getFeatures();
                features.forEach((feature) => {
                console.log(feature.getCoordinates());
                });

it says " feature.getCoordinates is not a function" .

The main purpose is to get the coordinates to campare them to pixel clicked on map.

In getting coordinates from features you must first get geometry by getGeometry() and then get coordinates from geometry by getCoordinates():

var coordinates = feature.getGeometry().getCoordinates();
