Retrieve array of objects from parent array of objects in ionic 3

Question

I have an array of objects as shown below

Array1
(4) [{_index: "sitelist", _source:{dma: 1 , site :4}},{_index: "sitelist", _source:{dma: 2 , site :4}},{_index: "sitelist", _source:{dma: 3 , site :4}},{_index: "sitelist", _source:{dma: 4, site :4}}]

Now i wanted to retrieve the source object and store it in an array , desired output should be

Array2 
(4) [{dma: 1 , site :4},{dma: 2 , site :4},{dma: 3 , site :4},{dma: 4 , site :4}]

I have tried using the filter function as

let Array2 = Array1.filter(function(obj){
                return obj._source;
            });

When i console.log(Array2) i am not getting the desired result, i am getting Array1 values, How to get the proper output, any help appreciated.?

Try this: Map

let result = Array1.map(x=>x._source)

You can use delete:

let Array2 = Array1.filter(function(obj){
                 return delete(obj._index);
             })
