AngularJS Question

How do i store an array of objects with angularJS

i have this schema of a object in mongoDB, i will call my object CAR in this question:

this.carroSchema = new Schema({
modelo: String,
ano: String,
placa: String,
cor: String,
categoria: [{tipo: String, preco: String}],
createdOn: {type: Date, default:}

and i have this function that gets the object CAR and stores in the array 'arrayCarros'

$scope.carregarCarros = function(){
method: 'GET',
url: '/listaCarro'
.then(function successCallback(response){
$scope.arrayCarros =;
}, function errorCallback(response){

if i do a select like this:

<select class="form-control" ng-click = "carregarCarros()" name="select">
<option ng-repeat = "carros in arrayCarros">{{carros.placa}}</option>

i have access to the propertie 'placa' from the object CAR, so i can show the values in my select.

but, my question is, how do i store the array 'categoria' that is inside of my object CAR, in other array so i can do a ng-repeat of him in my option and have access of his properties like 'tipo' and 'preco'?

Here is a simple way to do it. Obviously you could always use a built in javascript function like Array.filter or Array.reduce depending on your use case, but below is a simple to follow solution.

$scope.other_array = [];{


It should also be noted you can have multiple ng-repeats and just have one render and one render carros.categoria. That or just have both vars rendered within the same ng-repeat.
