Can't swap object inside object of two array

Now i have two array like this

$arr1 = [{
fullname: 'Foo1',
info: {
   age: 18,
   country: 'HN'
   }
},
{

   }
}]
$arr2 = [{
    fullname: 'Bar1',
    info: {

       country: 'HN'
       }

       country: 'HN'
       }
    }]

Now i want swap $arr1[0] with $arr2[1] but itsn't work. See my code

I tried the below code. It is working fine for me. 

$arr1 = [
    {
        fullname: 'Foo1',
        info: {
        age: 18,
        country: 'HN'
        }
    },
{
fullname: 'Foo2',
info: {
   age: 18,
   country: 'HN'
   }
}];
$arr2 = [{
    fullname: 'Bar1',
    info: {
       age: 18,
       country: 'HN'
       }
    },
    {
    fullname: 'Bar2',
    info: {
       age: 18,
       country: 'HN'
       }
    }];
    console.log($arr1[0]);
    console.log($arr2[1]);

    var temp = $arr1[0];
    $arr1[0] = $arr2[1];
    $arr2[1] = temp;

    console.log($arr1[0]);
    console.log($arr2[1]);

Output

sandeep@pc:~/Documents/Angular/Snippets$ node snippets.js
{ fullname: 'Foo1', info: { age: 18, country: 'HN' } }
{ fullname: 'Bar2', info: { age: 18, country: 'HN' } }
{ fullname: 'Bar2', info: { age: 18, country: 'HN' } }
{ fullname: 'Foo1', info: { age: 18, country: 'HN' } }

According to your original code snippet, you did not access array in an index based manner. $arr1[1] should be $arr1[0]. The following code should work.

temp = $arr1[0];
$arr1[0] = $arr2[1];
$arr2[1] = temp;

Technically speaking, swapping two variables with a temporary variable tempVar should work. Please try to debug your variable value with console.log(angular.toJson($arr1));
