Running into a problem starting up mongoDB - node.js

Question

I downloaded MongoDB with Compass and the shell as accessories and started learning from W3Schools Node.js MongoDB section.
Step 1: type into command prompt>npm install mongodb
success
step 2: create a MongoClient object file with this code and then save
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();
});
Step 3: Once the code above is saved run the file by calling it on the command prompt
C:\Users\MyName>node fileName.js
and this is the response I'm getting
C:\Users\*****\MongoDB Tutorials>node demo_create_mongo_db.js
C:\Users\*****\node_modules\mongodb\lib\utils.js:418
throw error;
