Over the past few weeks, the prettier javascript auto-formatter has come up many times in calypso-framework chat. For anyone who wants a fun introduction to what prettier is, feel free to watch the creators lightning talk at ReactConf: https://www.youtube.com/watch?v=hkfBvpEfWdA

tldw:

• Prettier auto-formats your code so you don't need to (DevEx++). A linter like eslint cannot reliably fix style issues (and also doesn't ensure standard formatting around things like linebreaks).
• It reduces the learning curve for new OSS contributors
• It acts as a teaching tool by wrapping expressions according to javascript's order of operations
• React, Immutable, jest, babel, and more are all using it (prettier is well tested)
• It is not very configurable. We would need to give up our WP/PHP inspired spacing conventions and break with WP Core JS Guidelines. We would need to modify our eslint config to conform to prettier. e.g. eslint-plugin-prettier.
• The initial "run prettier" commit would mess with our git blame. GitHub makes it pretty easy to skip around blame history

I think we all know that we could debate styles until the end of time, so I figure lets just call for a vote and be done with it. Should we spin up a PR that formats all of calypso, modifies our eslint style rules, and updates our docs?

Thumbs up for yes, thumbs down for no.
