@foxbunny
why that (comma expression) is not legal js?
@yunweb
return a, b, c;is not legal JavaScript. Normally, JavaScript parsers (including TypeScript) would throw a syntax error right there. What @jacobrabjohns suggests is the best way to do it.Personally, I think it’s cleaner to just use
this.$emit()anyway. It makes it clearer about when exactly it is going to be called and with what arguments, and decouples the implementation of your method from the stuff you want to emit. But that’s just me.
