How to use the @google-cloud/translate.v2 function in @google-cloud/translate

function main(
  projectId = 'YOUR_PROJECT_ID' // Your GCP Project Id
) {
  // [START translate_quickstart]
  /**
   * TODO(developer): Uncomment the following line before running the sample.
   */

  // Imports the Google Cloud client library

  // Instantiates a client
  const translate = new Translate({projectId});
