    { "ok" : 1 }

    The preceding code indicates that the command was executed successfully. Note that the response is returned to us in the JSON format.

  2. Let's pause for a minute and break down the preceding command so that we understand what we just did:

    • The db is a JavaScript object that represents the currently selected database. In our case, it is OrderBase.

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

In other words, working with MongoDB is actually a matter of issuing commands in pure JavaScript. Not only that, but the data itself and the responses to the commands are encoded...
