xo

rOpinionated but configurable ESLint wrapper with lots of goodies included. Enforces strict and readable code. Never discuss code style on a pull request again! No decision-making. No .eslintrc or .jshintrc to manage. It just works! 

Uses ESLint underneath, so issues regarding rules should be opened over there. 

JSX is supported by default, but you'll need eslint-config-xo-react for React specific linting.
