Hi Scott, That is fine. Maybe I did not explain the situation in enough detail or hit the point directly.
I understand that we can call a javaScript function in sparql or in another javascript function. I mean that when I say to call a function directly. But I bet a mechanism is required to call a function in a library because it is not in the file created in the workspace. For simple functions, such as abs(x), it is easy to re-create the code; but for complicated ones, re-creation is a waste of time. I would still search for ways to import them to the project.
