## booleanPointInPolygon

Takes a [Point][1] and a [Polygon][2] or [MultiPolygon][3] and determines if the point resides inside the polygon. The polygon can
be convex or concave. The function accounts for holes.

**Parameters**

-   `point` **[Coord][4]** input point
-   `polygon` **[Feature][5]&lt;([Polygon][6] \| [MultiPolygon][7])>** input polygon or multipolygon
-   `options` **[Object][8]** Optional parameters (optional, default `{}`)
    -   `options.ignoreBoundary` **[boolean][9]** True if polygon boundary should be ignored when determining if the point is inside the polygon otherwise false. (optional, default `false`)

**Examples**

```javascript
var pt = turf.point([-77, 44]);
var poly = turf.polygon([[
  [-81, 41],
  [-81, 47],
  [-72, 47],
  [-72, 41],
  [-81, 41]
]]);

turf.booleanPointInPolygon(pt, poly);
//= true
```

Returns **[boolean][9]** `true` if the Point is inside the Polygon; `false` if the Point is not inside the Polygon
