Normally we use $push to push or append the element or object into an array in mongoDB. But sometime we may need to push the multiple objects into mongoDB array document. Here below I'll try to explain how we can do that.
Let say I have a collection of favorite products and the collection name is favorite_products.

{
'productId':123,
'users':[
{'id':1,'name': 'saurabh'},
{'id':2,'name': 'gaurav'},
{'id':3,'name': 'coding4developers'}
]
},
{
'productId':124,
'users':[
{'id':4,'name': 'pankaj'},
{'id':2,'name': 'gaurav'}
]
}

Now in the above document, I wanted to push/append the multiple user objects into the users array whose product id is 124.
