Is it possible to write to the MongoDB console within a JavaScript execution?
To write on the console you need to use the print() method. The syntax is as follows - print("yourString"); To display the object, you can use printjson(). The syntax is as follows - printjson(yourObjectName); Let us implement these two functions. The first query is shown below to display something ->print("WelcometoMongoDBConsole"); Following is the output on the console - WelcometoMongoDBConsole Let us create an object. The query is as follows-&g

Check if MongoDB database exists?
There are two possibilities for checking if the MongoDB database exists. Case 1: The first possibility is that the MongoDB database exists, i.e. a specific index is returned. Case 2: The second possibility is that the MongoDB database does not exist, that is, index -1 is returned. Note: Indexing starts from 0 like an array and ends with (N-1). The syntax is as follows, which is used to check whether the MongoDB database exists. db.getMongo().getDBNames().indexOf("yourDatabaseName"); Case 1: Let us implement the above syntax to check whether the MongoDB database exists. The following is the query db.getMongo(
