Node.js MongoDB ObjectId to string

The result returned by `find` is an array.

Try this instead:

console.log(user[0]["_id"]);

try this:

objectId.str;

see [doc](

).

I'm using mongojs, and I have this example:

db.users.findOne({'_id': db.ObjectId(user_id) }, function(err, user) {
if(err == null && user != null){
user._id.toHexString(); // I convert the objectId Using toHexString function.
}
})

None of the above was working for me. I had to use
```ts
import { ObjectID } from 'bson';

(id as unknown as ObjectID).toString('hex');
```
In typescript

There are multiple approaches to achieve it ...
```
objectId.toString()
```
Using String Constructor
```
String(objectId)
```
Using Template Literals
```
const stringId = `${objectId}`;
```
Using Concatenation
```
const stringId = '' + objectId;
```
Using JSON.stringify
```
const stringId = JSON.stringify(objectId);
```
