How to sort collection of MongoDB Database in ascending order using Node.js ?
MongoDB, the most popular NoSQL database, is an open-source document-oriented database. The term ‘NoSQL’ means ‘non-relational’. It means that MongoDB isn’t based on the table-like relational database structure but provides an altogether different mechanism for storage and retrieval of data. This format of storage is called BSON ( similar to JSON format).
MongoDB Module: This module of Node.js is used for connecting the MongoDB database as well as used for manipulating the collections and databases in MongoDB. The mongodb.connect() method is used for connecting the MongoDB database which is running on a particular server on your machine. (Refer to this article).
sort() Method of MongoDB is used for sorting the documents. This method is used to define the ordering of the documents.

const connect = db.db(databasename);
const collection = connect.collection( "aayush" );
console.log( "Connection Created" )
const sort = { rollno: 1 }
collection.find().sort(sort).toArray((err, ans,) => {
