    node -e "new Function('console.log(\"hi\")')()"
or more to the point

    node -e "fetch('https://unpkg.com/cowsay/build/cowsay.umd.js').then((r) => r.text()).then(c => new Function(c + 'console.log(exports.say({ text: \"like this\"}))')())"
that one is particularly bad, because umd messes with the global object - so this works

    node -e "fetch('https://unpkg.com/cowsay/build/cowsay.umd.js').then((r) => r.text()).then(c => new Function(c)()).then(() => console.log(exports.say({ text: 'oh no'})))"

Well there you have it.

I had to laugh, because the post you're replying to STRONGLY reminds me of this story, https://news.ycombinator.com/item?id=31778490 , in which some people on the GNOME project objected to thumbnails in the file-open dialog box because it might be a "Security issue" (even though thumbnails were available in the normal file browser, something those commenters probably should have known about, but didn't, but they just had to chime in anyway).
