when i stored tag in mongodb database, I need to convert like this below.

tag = [ObjectId("58622e3bf39d570b21ece1b3"), ObjectId("58622e3bf39d570b21ece1a2"), ObjectId("58622e3bf39d570b21ece1r3")]

Assuming your using the node js MongoDB driver, you can use the ObjectID method. This will return an object instance of ObjectID. Use map and pass the function in.

const ObjectID = require('mongodb').ObjectID;

const objectIds = tag.map(ObjectID);
