After creating several npm script it becomes useful to run multiple scripts back-to-back in series. This is a nice feature because you can enforce that one script needs to complete before starting another one.

 

"scripts": {    "start": "node index.js",    "test": "npm run eslint && npm run stylelint && mocha spec/ --require babel-register",    "eslint": "eslint --cache --fix ./",    "stylelint": "stylelint '**/*.scss' --syntax scss",    "stylelint:fix": "stylefmt -R src/"  },
