Wow didn't realise you could omit braces + return! That instantly tidied up some code I'm working on right now, thank you so much.

Don't forget the two ways to write Arrow functions without a parameter

let f1 = () => 'hello from f1';

let f2 = _ => 'hello from f2';

Second one uses an underscore.
