I'm not 100% sure what you're asking, but if you're asking if it's possible
for C++ to have a reference to a JavaScript object, then yes, embind, which
is built into Emscripten, supports that:

https://kripken.github.io/emscripten-site/docs/porting/connecting_cpp_and_javascript/embind.html#using-val-to-transliterate-javascript-to-c

emscripten::val is implemented as a refcounted, JavaScript-side table of
references to JavaScript values.  The C++ code maintains indices into that
table.
