Querying object arrays with Mongoose - node.js

Question

Let's say I have such a collection in mongoose I have such a template
[
{
id: 123,
"arrayvalue": [
{
id: 355,
name: "jhon",
job: true
},
{
id: 155,
name: "clarck",
job: false
},
{
id: 275,
name: "orie",
job: true
},
]
}
]
I am currently using nodejs express
All I want to do is get objects whose value is true only.
I want the output to be like this
[
{ id : 123,
"arrayvalue": [
{
"id": 355,
"job": true,
"name": "jhon"
},
{
"id": 275,
"job": true,
"name": "orie"
}
]
}
]
I searched in many places and could not find it, I hope it is necessary for the project. you can help
I use : "mongoose": "^5.12.2"

var response = {};

Demo - https://mongoplayground.net/p/z1BwqmFh7Nq
$unwind
$push
$group
$match
db.collection.aggregate([
{ $unwind: "$arrayvalue" }, // break into individual documents
{ $match: { "arrayvalue.job": true } }, // match query
{
$group: { // join the document back
_id: "$_id",
arrayvalue: { $push: "$arrayvalue"}
}
}])
Option - 2
if you want to do it in JS :-
const data = [{
id: 123,
"arrayvalue": [{
id: 355,
name: "jhon",
job: true
},
{
id: 155,
name: "clarck",
job: false
},
{
id: 275,
name: "orie",
job: true
},
]
}]
const arr = data.map((d) => {
if (d.arrayvalue) {
d.arrayvalue = d.arrayvalue.filter(e => e.job === true);
}
return d;
});
console.log(arr);
