try to use && to launch both

  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject",
    "both": "npm run start && nodemon './backend/index.js'"
  },

How can I run multiple npm scripts in parallel?
