+# 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`.
