// A set of basic code conventions designed to encourage quality and consistency
// across your Sails app's code base.  These rules are checked against
// automatically any time you run `npm test`.
//
// > Note: If you're using mocha, you'll want to add an extra override file to your
// > `test/` folder so that eslint will tolerate mocha-specific globals like `before`
// > and `describe`.
// Designed for ESLint v4.

// you would visit `http://eslint.org/docs/rules/no-sequences`.  If you're unsure
// or could use some advice, come by https://sailsjs.com/support.
