Indeed. I also don't get from the article or the website what the intention is behind targeting webassembly first, instead of an intermediate that can be compiled to anything.

Grain already contains language features and a standard library which target the webassembly runtime, and maybe even the browser, explicitly.

It wouldn't make a lot of sense to compile the intermediate (which they probably have, anyway) to anything else.
