The problem is:
I have a collection of photos schema and likes schema, and inside photos there is an array of like ObjectIds called likeArray which is used to populate data from likes colletion.
But when i delete a like from likes collection, the ObjectId of that like in the likeArray still exists.
I tried to find the index of like._id in the likeArray and use likeArray.splice(index, 1) but couldn't work.
Can someone know the solution?
