Choose a Code formatting tool when you coding with JS

I wrote a basic source to make a route.
and I have a three different code formator were installed in my extension.

But, if I use the Prettier, line breaking is messed up like this.

and even there is no proper solution for this.

If you want, select the Beautify. it would be worked so well.
