_My question_:

I want to access a value in a certain array repetition.  
This is the JSON:

```auto
{
    "d": {
        "results": [{
                "Id": 1,
				"Value": "XX"
            }
        ],
        [{
                "Id": 2,
				"Value": "YY"
            }
        ]
    }
}

```

I would like to do something like this:

```auto
var jsonData = JSON.parse(responseBody);
console.log(jsonData.d.results[Id='1'].Value);

```

Is it possible?  
What’s the proper approach?

Thanks in advance

Here are a few examples of working with arrays…

```auto
const response = pm.response.json();
pm.test("Test", () => {
  pm.expect(response).to.have.property("id", 0);
  pm.expect(response.tags[0].id).to.eql(0);
  pm.expect(response.tags).to.have.lengthOf(1);
});

```

Here is an image to show the JSON layout, to compare to the assertions above.

For a consol log you could do;

`console.log(jsonData.d.results[0].id);`

Note that the [0] would be looking at the first item in the array… if you wanted the second it would be [1] third would be [2] and so on (remember array indexes start at 0).

Sorry, I think I didn’t explain myself properly.  
Maybe my example was to simple to explain what I was looking for.

I don’t want to access the value based on the index of the array (jsonData.d.results[0].value)), but on another value of the array (jsonData.d.results[Id=‘1’].Value).

In XPATH this is achievable without iterating all the entries, using expressions like:  
Get all the book which genre is Romance:

```auto
//book[genres/genre = 'Romance']

```

Thanks anyway.

Maybe try something like;

```auto
const response = pm.response.json();
_.each(pm.response.json().book, (book) => {
    if(book.genre === "Romance"){
        console.log(book.genre)
    }
})

```

You could also use [.find()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find) to get the object which has an `Id` of `1`

```auto
let obj = pm.response.json().d.results.find(e => e.Id === 1);
console.log(obj.Value);

```
