ESLint comes with a preset that implements a logical set of defaults that can save you a lot of time. It decides what is a warning and error for you and enables the rules that it thinks make the most sense for most people.
HopeJS uses ESLint's standard rules as a good shortcut to get started, then I tend to tweak a few of the settings based on our team's feedback and the project requirements.
This is a nice compromise because it avoids the work of starting from scratch, but it still offers complete power in tweaking the settings as we see fit.
We could go a step farther and use an existing set of rules like airbnbs, XO, or standard JS. Assuming that you don't mind the decisions that they've made, this is a great way to avoid spending a lot of time arguing about all the decisions that I just discussed previously.
