Is there an easier way to get a document's Id? about firestoregoogleappsscript HOT 3 CLOSED

  var collection = "CollectionName";
  var projectID = "projectid";
  var newDoc = {
    name : "John",
    year: 2020,
  } 

var result = firestore.createDocument(collection + "/", newDoc); // machine name
  //Original Thought
  var returnID = result.name.replace("projects/" + projectID + "/databases/(default)/documents/" + collection + "/", "")
  Logger.log("Parsed returnID: ",returnID);
  
  //NEW Thought
  var rn = result.name;  //This returns the long path to the document
  var regex = /[^\/]+$/; //This looks for the last slash in that path, and matches everything after (the auto id)
  var id = rn.match(regex); // << EXAMPLE SOLUTION
  //var id = rn.match(/[^\/]+$/); // << ONE LINE SOLUTION
  Logger.log("Auto ID is: " + id);
