Is it possible to have object with value only?

Question

Is it possible to have object with value only?

I have this piece of code :

db.collection('coders', function(err, collection) {
        collection.find(toFind).toArray(function(err, items) {
            res.send(items);
        });

where toFind is something like {"position":2,"$or":[{"position":{"$lt":20}},{"name":"whatever"}]} It is a String, so the previous code doesn't execute, because it needs an object. I already know, that I can create object from String like

var obj={}
obj[key] = {value}

But how can I create an object without key ?

javascript
node.js
node-mongodb-native

Answer 1

To convert toFind from a string into an object that you can pass into find, use JSON.parse:

toFind = JSON.parse(toFind);

Answer 2

Everything in JavaScript is an object. However, what you apparently want is a simple variable:

obj[key] = value;

The object you posted above would be defined exactly like this:

var obj = {
    "position": 2,
    "$or": [{
        "position": {
            "$lt": 20
        }
    }, {
        "name": "whatever"
    }]
};
