How do I reverse the coordinates with mongodb?

I have these coordinates in the wrong order I need to reverse them for all collections:

{
  _id: ObjectId("638f9866d9014fabfc47275e"),
  address: '801 Pine St, Anchorage, AK',
  name: 'Russian Jack Skatepark',
  location: { type: 'Point', coordinates: [ 61.214855, -149.793563 ] }
}

>Solution :

You can use $reverseArray as follow:

db.collection.update({},
[
{
$set: {
  "location.coordinates": {
    $reverseArray: "$location.coordinates"
   }
  }
 }
])
