Node.js MongoDB Creating Database giving error

Question

var MongoClient = require('mongodb').MongoClient;
var url = "mongodb://localhost:27017/mydb";

MongoClient.connect(url, function(err, db) {
  if (err) 
  {
  throw err;
  }
  console.log("Database created!");
  db.close();
});

This is the error I am getting when executing this code in nodejs and trying to create a database, I was going through the tutorial in w3school, please help to solve this error--

You actually need a MongoDB server to be running. That does not come with the node driver BTW. You probably assumed your `npm install` did that. It did not. Install a server [Install MongoDB Community Edition on Windows](https://docs.mongodb.com/manual/tutorial/install-mongodb-on-windows/) — Neil Lunn, Jun 12 '17 at 14:02

Make sure that you have Mongo running on on port 27017 use this to verify

mongo localhost:27017
