remove doesn't work

[kazzacarrot]

After my solution didn't pass, and I couldn't debug my own,
I copied your solution into "re.js" and ran 'learnyoumongo run re.js` -> This is the output

Expected document to be removed [ { _id: '554a655c0639034860349353', name: 'blah' } ]

@kazzacarrot Here's my code if you want to compare - it passes run and verify. In the official MongoDB Node api notes, remove() has been deprecated in favor of deleteOne() or deleteMany().

var mongo = require('mongodb').MongoClient;

var url = 'mongodb://localhost:27017/'+process.argv[2];

mongo.connect(url, (err, db) => {
        if (err) throw err;
        var coll = db.collection(process.argv[3]);
        var id = process.argv[4];
        coll.deleteOne({
                _id: id
        }, (err, data) => {
                if (err) throw err;
                db.close();
        });
});

@hwangm, I copy pasted your code and it still shows the same error for me.

@snehal96 Have you looked at the solutions updated for mongodb 3+?
https://github.com/nachoperassi/learnyoumongo

Perhaps there was some change that makes my solution invalid now, I'm not sure since it was a while ago now.
