Now that we have created a database, let's populate it with some collections by performing the following steps:
Run the following to create a collection for
Products:> db.createCollection('Products')MongoDB will respond with the following:
{ "ok" : 1 }The preceding code indicates that the command was executed successfully. Note that the response is returned to us in the JSON format.

createCollection('Products')function is one of the many member methods ofdb. Needless to say, it creates a new collection and adds it todb. Its parameter, a string, is the name of the new collection.
