Update code formatting about sentiment HOT 2 OPEN

I think with the work coming in as part of #128 I'd be happy to do a major version change and update the minimum engine to Node 8. Yay ES6 syntax! 🎉

I'd prefer to keep the style stuff where it is. It's a lot of work to maintain so many repos (personal, Scratch, Mozilla, etc.) and it's really helpful to have one consistent set of style rules across my stuff.

Update: with 5.0.0 we have updated the minimum engine to Node 8.0.0. Happy to accept PRs that migrate over to usage of const, let, arrow functions, and ES6 class syntax. Note that our eslint config will need to be updated at the same time.
