I noticed a question on the PMC Slack channel if there were any kind of formal coding styles?
It seems like we don't have much of any, beyond starting to use a new @cordova/eslint-config which seems to be based on semistandard (with indent spacing of 4) and almost the same as how we have linted for a few years. I think this is a nice starting point, definitely wouldn't mind something more fancy, such as an adaptation of prettier-standard, someday in the future. (Fair disclosure that prettier-standard uses a Prettier fork that I have been maintaining.)
