Generate hexagons in JS based on center coordinates and radius

function drawHexagon (centerPointLatitude, centerPointLongitude, radiusLength) {
  const radius = radiusLength / 6371

  const angle = 2 * Math.PI / 6 // 2PI (360 degree) divded by 6 points of the hexagon shape

  const hexagon = []
  for (var i = 0; i < 6; i++) {
    const longitude = centerPointLongitude + (radius * Math.cos(angle * i))
    const latitude = centerPointLatitude + (radius * Math.sin(angle * i))

    hexagon.push([longitude, latitude])
  }

  // close the polygon adding the initial point
  hexagon.push(hexagon[0])

  return hexagon
}
