WASM is another VM and it reminds me of the difficulty that the JVM has faced. You can write-once-run-once a lot of languages like Ruby or JavaScript on the JVM and some of the runtimes are pretty good. But the rest of the community prefers using the original implementation. If some library that you want to use doesn’t work, no one is going to help you. You’re using the second class implementation.
