How to use the @turf/boolean-within function in @turf/boolean-within

var bboxWidth = (east - west);
    var bboxHeight = (north - south);
    var columns = Math.floor(bboxWidth / cellWidth);
    var rows = Math.floor(bboxHeight / cellHeight);
    // adjust origin of the grid
    var deltaX = (bboxWidth - columns * cellWidth) / 2;
    var deltaY = (bboxHeight - rows * cellHeight) / 2;

    var currentX = west + deltaX;
    while (currentX <= east) {
        var currentY = south + deltaY;
        while (currentY <= north) {
            var cellPt = point([currentX, currentY], properties);
            if (mask) {
                if (within(cellPt, mask)) results.push(cellPt);
            } else {
                results.push(cellPt);
            }
            currentY += cellHeight;
        }
        currentX += cellWidth;
    }

    return featureCollection(results);
}

    return (fieldPolygon: any) => within(fieldPolygon, queryPolygon);
}
