convert string array to objectid mongoose

let objectIdArray = stringObjectIdArray.map(s => mongoose.Types.ObjectId(s));
//or
let objectIdArray = stringObjectIdArray.map(mongoose.Types.ObjectId);

Here is what the above code is Doing:
1. We’re using the map() method to iterate over each string in the array.
2. We’re using the mongoose.Types.ObjectId() function to convert each string to an ObjectId.
3. We’re returning the ObjectIds to a new array.

Now that we have an array of ObjectIds, we can use the $in operator to query for all documents with an _id that matches any of the ObjectIds in the array.
