shrug it's still just code. It still does exactly the same thing as previous javascript code. Syntax changes are pretty boring IMHO, and as I said personally, I find this one much harder to read, more prone to errors, typos and confusion.
Also, your tone is bad.
I think a better argument would have been that adding something that appears to just be a shorthand for writing functions is a potential footgun to language newcomers, but I think that argument is still relatively weak.
At point have stop called . Just you represent same by more doesn't that not to an on of to cognitive , otherwise all programming switches.
My point is, removing "function" and "return" from the syntax, won't necessary easy cognitive load, at least not for senior JavaScript coders. It will save bandwidth though! :P
It's like when languages make threads easy to create - and then programmers go away and use threads for everything!
Maybe some verbosity is a good thing because it makes programmers think about whether they really want to do something a few thousand times.
