Compiling code from C++ to WASM is counter-productive if the native JavaScript is fine. It's just that native languages seem to perform quite a bit better in the domains of graph construction, graph optimization, and even basic string manipulation.
When did WASM come into the picture? I use Parcel because my time is valuable and I don't want to master the arcane arts of modern JS build toolchains but I still NEED to benefit from them if I'm to run a successful business and make sure my investors get their money back and a language I can deliver plain text over HTTP/S that runs performantly across billions of devices that I can modify on the fly is beyond valuable.

C++ isn't going to help me deliver my product to my customers in any measurable way that influences the outcome of our relationship. JavaScript, frankly, does - the less time my organization spends writing code, the less we have to charge for things to make up for that margin impact.
Believe it or not, some people have problems in domains with contexts that have nothing to do with yours and the things they come up with are equally valid solutions.
