Usually you would pick a config you like and set it up for your project, notable ones are already mentioned but I'll mention more:

You might enjoy `xo` :) https://github.com/xojs/xo

XO

The developer told me we could not do that because the linter we are using. (XO)[https://github.com/xojs/xo] started complaining.

Real world example: you are using create-react-app, and you want to also to use xo, as both come with their own version of ESLint pre-installed, you could end up with 2 ESLint installed.

One of the biggest hassles to update was the linter we are using: XO, which is a very opinionated, but customizable linter base on ESlint.
