As mumphster pointed out in a sibling, 15MB of wasm vs 15MB of javascript is an unfair comparison. For instance, my aforementioned app is a few hundred KB of uncompressed js when rewritten, not 15MB. Also, in my experience, a 15MB wasm blob has shit caching characteristics; it gets evicted all the time. An immutable few hundred KB js blob, on the other hand, can remain cached for much longer. Sure, you can use a service worker and its Cache API to make caching large blobs more predictable, but then shipping new code / cache invalidation becomes more annoying.
