Accessing an array within an object

Question

var oldMatches = Meteor.users.find(userId, {
    fields: {
        _id: false,
        matches: true
    }
}).fetch()

This returns an object with an empty matches array, as it should. How would I access this array to find the length of it?

Thanks.

Then `oldMatches` is not an object, like you claimed. You probably want `oldMatches[0].matches.length` then. — Felix Kling, Mar 30 '15 at 14:16
That is so weird! When I console log oldMatches I get [object Object] and when I run the query on the client I receive an object with an array inside... But this works. Thank you! — Nathan, Mar 30 '15 at 14:30

You would find the length of the array with

oldMatches.length

So:

if(oldMatches.length) {
    // is not empty
} else {
    // is empty
}

N.B. length only works on a returned array from fetch, not a Meteor cursor

oldMatches.length gives me the length of 1, because it contains 1 array. I need the length of the array. I've tried oldMatches.matches.length, which is what I assumed would work, but it's not. – Nathan Mar 30 '15 at 14:14
