Push Item From One Array Into another Array in Angular

Question

I am programming an app with AngularJS and wanted to know how to push an item from one array into another array.

Here is sample code:

$scope.tasks = [
     {title: "Do the dishes"},
     {title: "Walk the dog"},
];
$scope.addToTasksDone = function() {// IM FAILNG HERE};
$scope.tasksDone = [];

How can I push the item with value "Do the dishes" to the tasksDone array?

Solution 1

$scope.tasks = [
{title: "Do the dishes"},
{title: "Walk the dog"},
];
$scope.tasksDone = [];
$scope.addToTasksDone = function(index) {// IM FAILNG HERE};
$scope.tasksDone.push($scope.tasks[index]);
}

Solution 2

$scope.tasks.push(yourObject)

this question was aked before here

Solution 3

$scope.tasks = [
    { title: "Do the dishes" },
    { title: "Walk the dog" }
]; 
$scope.tasksDone = [];
for(var i in $scope.tasks){
    $scope.tasksDone.push($scope.tasks[i]);
}
