I personally hate people that are omitting curly braces for single statement if/else blocks just as much as I hate people that are omitting parentheses when assigning "arrow functions"
that take only one argument to a variable or a constant (even though that particular case is mainly "just" offence in regards to code readability /glanceability. )
But this comma convention thing (in most language that is not optional...) is one of the rare things that are shared between most of the languages... or so I believed
