I'm not an expert, but my understanding is that with Web Assembly you essentially have to ship the whole language if you're doing dynamic languages, so it greatly inflates the size of the package the user has to download. The one I've been looking to the most is Rust, as it compiles to a smaller size, doesn't have a GC to ship (by default), and is not C/C++. C/C++ seem to be the other common WASM languages. Edit: Just saw you're a beginner programmer, I probably would not suggest Rust as a first language. Web Assembly in general may not be a good starting point, but if you're set C++ might be slightly better. (I tend to suggest Python as a starting language)
