Answer 1

Something like this should work:

db.collectionName.update({
     "tasks.title": "new to d odo "
}, {
    $set: { "tasks.$.done": true }
})

You can check more details in the documentation .

Answer 2

you can use

$push

$set

$addToSet

you can use these operators to insert any object or any value to an array in the mongoose model.
