    // A set of basic code conventions (similar to a .jshintrc file) 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`.
    //
    // > An additional eslintrc override file is included in the `assets/` folder
    // > right out of the box.  This is specifically to allow for variations in acceptable
    // > global variables between front-end JavaScript code designed to run in the browser
    // > vs. backend code designed to run in a Node.js/Sails process.
    //
    // > 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.
