Dear Prof Wolfgang,
I been trying to do cubical spline for a set of data to produce a smooth curve.
I open your file here

https://www.compadre.org/osp/items/detail.cfm?ID=11478

there are a lot of old java syntax that I don't know how to convert to JavaScript equivalent. For example.

1. in Variables tab, spline is a type ==CubicSpline, how do I convert to JavaScript?
2. in fixed relationship, code like "y[i]=((org.opensourcephysics.numerics.CubicSpline)spline).evaluate(xi);" is this kind of code working on EJSS or only EJS currently?

I lack the technical knowledge of harnessing the org.opensourcephysics.numerics.CubicSpline library,  Thus, can an EJSS (Javascript) version be released soon? :)

Thank you very much.
