simplify(polyline, limit)

polyline
- array of points representing a polyline, each point represented by coordinate array[x, y]
limit
- number of points/vortexes that will remain in the resulting polyline
simplify(polyline, limit, areaFn)
You can specify a custom areaFn

an array of {x, y}
objects you can use something like this:
