Hello there,

[TLDR: I'm curious to know the degree to which including a pure javascript 
program (via the V8 package) in an R package affects the potential of passing 
CRAN review]

I'm working on implementing an R package to support users of the Psych-DS data 
specification<https://github.com/psych-ds>. The package will include a shiny 
app with helpful functions for assembling and publishing high-quality datasets 
in the behavioral sciences, but one of the core functions will be to validate 
existing datasets (local directories) according to the rules of our schema.

We already have this validator functionality set up as a Deno application, and 
we can use certain Deno tools, along with esbuild, to generate node-based and 
pure-javascript bundled versions of validator.

We'd like to be able to leverage our existing code instead of having to 
reinvent the wheel for the R context. If we try to publish our package to CRAN 
with this javascript script as a core part of the package's functionality, will 
that severely affect our chances of passing the review process? I know that 
having sufficient unit tests and well documented processes is crucial to 
getting a package through, but the validator code in this scenario would be 
stringy and minified, and the bundle would not include unit tests for all the 
validator's internal functions. Is it the case that a dependency like this is 
equally subject to CRAN review scrutiny, or would it be sufficient to have all 
the R-based components comply with CRAN requirements?

Thanks,
