@turf/line-slice

lineSlice

Takes a [line][1], a start [Point][2], and a stop point
and returns a subsection of the line in-between those points.
The start & stop points don't need to fall exactly on the line.

This can be useful for extracting only the part of a route between waypoints.

* line ([Feature][4]<[LineString][1]> | [LineString][1]) line to slice

``javascript
var line = turf.lineString([
[-77.031669, 38.878605],
[-77.029609, 38.881946],
[-77.020339, 38.884084],

[-77.021884, 38.889563],
[-77.019824, 38.892368]
]);
var start = turf.point([-77.029609, 38.881946]);
var stop = turf.point([-77.021884, 38.889563]);

var sliced = turf.lineSlice(start, stop, line);

//addToMap
var addToMap = [start, stop, line]
`

Returns [Feature][4]<[LineString][1]> sliced line
