TurfMisc#nearestPointOnLine index is not correct in some cases

[Blafasel3]

We encountered following problem in our project:
When we pass a list to the above mentioned method and if the last point in the list is the closest point, the index returned by the matching feature is List.size - 2 .

I would expect the index to be List.size - 1.

In the following code snippet the index seems not to be set correctly:

Imo it should say

      if ((double) stop.getNumberProperty("dist")
        < (double) closestPt.getNumberProperty("dist")) {
        closestPt = stop;
        closestPt.addNumberProperty(INDEX_KEY, i + 1); // the index of the closest point is i + 1, not i
      }
