I want to get the number of documents in the collection(MongoDB) and then use this variable in another function. But I don't understand why I can't record the result in var above-mentioned?

var countD;
db.db("mongouploads").collection("blocks").countDocuments({}, {}, (err, result) => {
    if (err) throw err;
    countD = result
});

And then countD equal undefined. Where is my fault?

Use `count` instead of `countDocuments `. like `db.getCollection('Model').count({})` – IftekharDani Oct 30 '18 at 07:15
