AngularJs check weather Array containing an item or not

Question

I have array of name:
$scope.myArray with some values.
Now I want to check an Item is present in array or not,
If it is not present then I want to push that item into array and If that item is already in array then I don't want to push it.
Please tell me how to do this ?

if($scope.myArray.indexOf(item) === -1) {
    $scope.myArray.push(item)
}

You can read about indexOf for more details. Also, checkout underscore js for some readily available functions.
