# MongoDB: deleting a document from a collection
|
|
|
|
```js
|
|
async function deleteCourse(id) {
|
|
const result = await Course.deleteOne({ id: id });
|
|
console.log(result);
|
|
}
|
|
```
|
|
|
|
Use `findByIdAndRemove([id])` if you want to return the value that is deleted.
|
|
|
|
If we were to pass a query object that matches multiple documents in the
|
|
database to `deleteOne` it would only delete the first document returned. To
|
|
delete all use `deleteMany`.
