Whereas V8:
https://cran.r-project.org/web/packages/V8/vignettes/v8_intro.html
seems the go-to Javascript interpreter available within R (R is the preferred environment of Junling, Matt Parker, Andriy and others):
Drawing on my familiarity with intra-language interoperability, may I draft an interface code making your simulation available programmatically, within R? To support operations e.g. mutual calibration + validation
Thoughts?
