  1. I am currently working mongodb and nodejs from w3schools website. I have seen an error in a code. https://www.w3schools.com/nodejs/nodejs_mongodb_create_db.asp In this website there is a code for creating website. : 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(); }); When I run this, I see this on the terminal: (node:26812) DeprecationWarning: current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor. Database created! I needed to change 3rd line. old 3rd line: MongoClient.connect(url, function(err, db) { new 3rd line: MongoClient.connect(url, {useUnifiedTopology: true}, function(err, db) {
