can’t we use `.forEach(res =&gt; {return res});` or something better than that ?

Yes, if you use TypeScript and target ES5. I use arrow functions all the time..

in fact, since simple expressions automatically return themselves you could write your contrived snippet as just `.forEach( res =&gt; res )`

I recognize that wasn't a real example, but plenty of real world one-liners exist and it's nice to not need a `return` statement cluttering things

<@U61TENRBJ> or you can use babel to compile the file before uploading to NS.
