VSCode - ESLint, Prettier & Airbnb Setup

  "extends": ["airbnb", "prettier", "plugin:node/recommended"],
  "plugins": ["prettier"],
  "rules": {
    "prettier/prettier": "error",
    "no-unused-vars": "warn",
    "no-console": "off",
    "func-names": "off",
    "no-process-exit": "off",
    "object-shorthand": "off",
    "class-methods-use-this": "off"
  }
}

Airbnb flat config is still not supported by the airbnb and airbnb-base so I suggest trying this one instead: eslint-config-airbnb-extended. It’s really good, up-to-date, and supports new tools like import-x and stylistic. Plus, it has helpful CLI support too!
