## rectangleGrid

Creates a grid of rectangles from a bounding box, [Feature](https://tools.ietf.org/html/rfc7946#section-3.2) or [FeatureCollection](https://tools.ietf.org/html/rfc7946#section-3.3).

**Parameters**

-   `bbox` **[Array](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Array)&lt;[number](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number)>** extent in [minX, minY, maxX, maxY] order
-   `cellWidth` **[number](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number)** of each cell, in units
-   `cellHeight` **[number](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number)** of each cell, in units
-   `options` **[Object](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object)** Optional parameters (optional, default `{}`)
    -   `options.units` **[string](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** units ("degrees", "radians", "miles", "kilometers") that the given cellWidth 
        and cellHeight are expressed in. Converted at the southern border. (optional, default `'kilometers'`)
    -   `options.mask` **[Feature](https://tools.ietf.org/html/rfc7946#section-3.2)&lt;([Polygon](https://tools.ietf.org/html/rfc7946#section-3.1.6) \| [MultiPolygon](https://tools.ietf.org/html/rfc7946#section-3.1.7))>?** if passed a Polygon or MultiPolygon,
        the grid Points will be created only inside it
    -   `options.properties` **[Object](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object)** passed to each point of the grid (optional, default `{}`)

**Examples**

```javascript
var bbox = [-95, 30 ,-85, 40];
var cellWidth = 50;
var cellHeight = 20;
var options = {units: 'miles'};

var rectangleGrid = turf.rectangleGrid(bbox, cellWidth, cellHeight, options);

//addToMap
var addToMap = [rectangleGrid]
```

Returns **[FeatureCollection](https://tools.ietf.org/html/rfc7946#section-3.3)&lt;[Polygon](https://tools.ietf.org/html/rfc7946#section-3.1.6)>** a grid of polygons
