It shouldn't be necessary to write them in the first place.
Anyway in this case I guess some automatic code reduction tool has decieded that four characters can be saved by changing it to commas. I doubt it was written that way to begin with.

I love Go's lack of semicolons but I don't extend that to some foolhardy attempt to write JavaScript without semicolons. In JavaScript, support for proper semicolon-less style is clearly lacking in practice if not in spec (if it weren't lacking this wouldn't be a oft-recurring story, but it is).
