Supports TypeScript\n- Supports both CommonJS and ESModules\n\n\n## Getting Started\n\n```sh\n$ npm install --save is-lo # for npm users\n$ yarn add is-lo           # for yarn users\n```\n\n##

from 'node:os'\nimport { isLo } from 'is-lo'\n\nconst interfaces = os.networkInterfaces()\nconst names = Object.keys(interfaces)\n\nconsole.log(isLo(interfaces[names[0]])) // true or false\n```\n\n### CommonJS\n\n```js\nconst os = require('node:os')\nconst { isLo } = require('is-lo')\n\nconst interfaces = os.networkInterfaces()\nconst names = Object.keys(interfaces)\n\nconsole.log(isLo(interfaces[names[0]])) // true or false\n```\n\n## Reference\n### `isLo({ family: 'IPv4', address: '127.0.0.1' })`\n### `isLo([ { family: 'IPv4', address: '127.0.0.1' }, ... ])`\n- `family` (string): `'IPv4'` or `'IPv6'`\n- `address` (string): IP address\n- **Result** (bool): true if it is loopback network interface\n\n## Development\n### Test\n\n```\n$ yarn test\n```\n\n### Publish\n\n```\n$ yarn publish\n```\n\n## License\nMIT \u0026copy; [Pine
