database.counter.count throws error

[lauriek]

I am trying to test the DatabaseCounter count method; per the documents both the parameters (id and callback) are optional. So when I run the following
var dbNewsletter = db.load('db/newsletter.nosql'); var mycounter = dbNewsletter.counter.count('id'); console.log(mycounter)

I get the following

Counter {

@biomade dbNewsletter.counter.count('id'); because it doesn't contain any callback ....

I tried that too
code:
var dbNewsletter = db.load('db/newsletter.nosql');
var mycounter = dbNewsletter.counter.count('id');
console.log(mycounter)

and this is the error I got
Counter {

db:

filename: 'db/newsletter.nosql',
filenameTemp: 'db/newsletter.nosql-tmp',
filenameMeta: 'db/newsletter.meta',

That's what I have been looking at... which really isn't helping.

[Peter Širka]

dbNewsletter.counter.count('id', function(err, response) {
    console.log(response);
});

[lauriek]

Yes, but why does the documentation say the parameters are optional, and when I do put in the parameters, I get a ZERO as a result and I have 4 records in my db
{"id":1,"name":"laurie","email":"[e-mail]"}
{"id":2,"name":"erich","email":"[e-mail]"}
{"id":3,"name":"mary","email":"[e-mail]"}
{"id":12,"name":{"first":"jon","last":"doe"},"address":{"street":"123 main","city":"NYC","state":"NY","zip":"11760"}}

[Peter Širka]

I have fixed documentation.
