I don't know how to print mongodb query results using the nodejs native driver

I'm storing a single word in the database using the following:

collection.update({},{$set:{word:newWord}},{upsert:true},function(){
    collection.find().nextObject(function(err, results) {
        oldWord = results;
        console.log("New Word: " + results);
    });
});

here is an example of my DB

{ "_id" : ObjectId("4ff92def446ce41df5692385"), "word" : "asdf" }

Every time it gets to the console.log line, it looks like:

New Word: [object Object]

I'm trying to isolate "asdf" (sans quotes) from the above record. I've tried everything from toArray, nextObject, etc.

What am I missing? I've been trying for hours!

In node, you can just use: console.log("New Word: ", results); (note the comma).

Another option: console.log( JSON.stringify(results) );

It will print something like: { "_id" : "4ff92def446ce41df5692385", "word" : "asdf" }

I don't really agree that the "string representation of objects in Javascript isn't very helpful." I find it helpful, at least.

You can either override the toString Method of you result object as described here: http://blog.anselmbradford.com/2009/04/05/object-oriented-javascript-tip-overriding-tostring-for-readable-object-imprints/ or simpy just print the property you want to show by specifying it object.propertyname.

If you're interested in some field, you should print that, not the whole object (mainly because string representation of objects in Javascript isn't very helpful).

 console.log("New Word: " + results.word);
