JSON is a serialization format based on js syntax. It’s not the same as JavaScript, it’s usually stricter. Those stricter rules are designed to make it easier to parse. In actual js, trailing commas are just fine (although i think some versions of internet explorer parsed them as nulls for some reason.)
Yeah, I fall for that so often. Can’t move or delete lines without double-checking that you didn’t accidentally leave a comma at the end…
And javascript is otherwise so lax! You like semicolons? Put as many of them as you want wherever you like! Or don’t.
