How to make Prettier add commas for objects

[erhanertem]

I can't get Prettier in JS to add commas in VScode automatically. Is it now and then a usual behaviour ? I searched stackoverflow and there are mentions of Prettier being able to set commas at the end of each object literal property dated back to year 2020.

Note: Prettier puts comma only if one line of property is given and on-save the line receives comma. However, in the event of multiple properties, on-save none receives a comma.

iataCode: 'LH' , <-here
bookings: [] ,<-here
};

Commas must always be added by you, the last comma is optional and prettier adds it:
