Push list of objects to another object in angularjs

I have two separate objects which is shown below

Object1 =  [{value:'A/B'},{value:'A/B/C'},{value:'A/F'},{value:'A/'}];

Object2 =[{option:'A/'},{option:'A/B'}];

Now i need to modify the Object2 by adding a new attribute so that the Object2 must look like this

 Object2 = [{option:'A/',
            directories:[{value:'A/'},{value:'A/B'},{value:'A/B/C'},{value:'A/F'}]},
           {option:'A/B',
            directories:[{value:'A/B'},{value:'A/B/C'},{value:'A/F'},{value:'A/'}]}];

The changes what i need is

I have tried the following code

angular.forEach(Object2,function(value,key){

 angular.forEach(Object1,function(value,key){

        //I need the code here

  });
});

Try the following

  angular.forEach($scope.Object2,function(value,key){
      value.directories = angular.copy($scope.Object1);
      for (var i=0; i < value.directories.length; i++) {
        if (value.directories[i].value === value.option) {
            var item = value.directories.splice(i,1);  
            value.directories.unshift(item[0]);
            break;
        }
      }
  });

basically after adding the directories array to your object you can find the index of the object that you want in the start of array remove it and add it back to the beginning of the array.

Why are you iterating twice? You can use just one forEach loop and an arrow function with destructuring:

angular.forEach($scope.Object2, { directories } => directories = $scope.Object1);
