Thanks for taking the time to suggest some changes! Can you elaborate a bit on how this actually improves things?

not only is it shorter and giving you the possibility to omit const when it isn't needed. It also gives a better error message in the stacktrace/log

Because the function name appears in the error log, named functions are highly useful in debugging and determining which function produced an error.

it don't have huge benefits, it just comes down to preferable taste like immutable or mutable, colon vs non-colon or tab vs space... so if you like to reject this PR, then that is fine...

I guess if i would have sticked with the const syntax then i would have made this into a one liner to omit return and function keywords instead by using arrow fn

const now = () => new Date().toUTCString()

i'm a nerd when it comes to byte saving technic sometimes.
