On that knob -- I prefer 80 characters today because it allows me to place two panes of code side-by-side without wrapping on one monitor. Sometimes I throw in a REPL pane as well as or instead of the second pane.

But I also have come to like prettier's approach. At least, I did last time I used it a year or two back. Almost no configuration, no bikeshedding, it just reformats your js code and doesn't sweat the rest. It's not having every style exactly how I like it, but it's much nicer than the eslint/jshint/etc hell I used to configure. Of course to some extent these tools solve some different problems but I didn't really feel much of a need to keep eslint around once prettier started enforcing its standards.
