Checks to see if a point is inside of a polygon.
Examples of Turfjs visualized with mapbox.js
determine whether two geojson objects are equal
Takes a bounding box and a cell depth and outputs a feature collection of points in a grid.
Makes outer rings cw, inner rings ccw. Or reversed
Clips a Feature by a bbox
find the union of geographic features
Divide a linestring into segments of specified length
erase spatial features
Calculates the distance between two point features in degrees, radians, miles, or kilometers.
Turf flatten module
Buffers a point, linestring, or polygon Feature/FeatureCollection to a given radius. Units supported are miles, kilometers, and degrees.
Takes a FeatureCollection of points with z values and an array of value breaks and generates filled contour isobands.
find the intersection of features

an example of how to use Turf for a scripting task with node.
Segment a LineString by Features
Takes a set of overlapping polygons and returns non overlapping donuts.
Create voronoi polygons from a set of points
Vincenty's direct formula computes the location of a point which is a given distance and direction from another point.
Vincenty's inverse formula computes the geographical distance and direction between two given points.
