Display collections in a particular MongoDB database?

At first, switch to a particular database in MongoDB with the USE command as in the below syntax −

use yourDatabaseName;
db.getCollectionNames();

Let us implement the above syntax to display collections of database WEB −

> use web;
   switched to db web
> db.getCollectionNames();

This will produce the following output −

[
   "2015-myCollection",
   "2015-yourCollection",
   "2019-employeeCollection",
