Ping IP Address in React Native

ping.js

fetch('http://localhost')
  .then((response) => {
    console.log('response ', response)
    if (response.status === 200) {
      console.log('success')
    } else {
      console.warn('error')
    }
  })
  .catch((error) => {
    console.error('network error: ' + error)
  })

just a heads up. It doesn't work when you try to ping (fetch) an http URL from a https host.
