API response array data prefixing with 'u'

I am receiving the object in the API response - Like the below one:

{
    "title": "abc",
    "type": 3,
    "created_at": "2018-10-08T14:04:25",
    "description": "des",
    "data": {
        "response": "[u'9952d1fa', u'ffb1344d', u'a3730337', u'bde08960']"
    }
}

Now I want to parse the response which is in the data key. But the JSON.parse on the response is giving error.

Any idea how to parse this in javascript or should we handle this in the backend (Python-Django)?

I have already checked this link, but there is no solution in Javascript

the key:value pairs should be separated by a comma, so that is not a valid JSON – Fabrizio Calderan Oct 10 '18 at 10:12
It's hard to tell how you are generating the response above? It seems like a Python list stringified, and not a JSON result. Can you elaborate? – Jonas m Oct 10 '18 at 10:17
If you've just logged the response Python has given you and trying to parse that, it's not valid JSON. If you're outputting it programatically to JS then it won't have the `u`'s. – Ben Fortune Oct 10 '18 at 10:19
@fcalderan, I just posted the preview from the network. – Varun Chakervarti Oct 10 '18 at 10:25
@Jonasm, This is what I am getting from the REST API and yes the backend is in (Python-Django) – Varun Chakervarti Oct 10 '18 at 10:26
@BenFortune, I want to use the response as an array to loop in. Yes, I am calling the API and saving the result in another object. – Varun Chakervarti Oct 10 '18 at 10:31
In that case, your backend does not seem to be giving you proper JSON. Or rather it *does* but it's not formatting it as it should - it seems to simply be turning the array into a string representation and posting that which is a valid string but not a valid array in JSON. – VLAZ Oct 10 '18 at 10:39
@vlaz, That means I have to update the API response not the handling/parsing. – Varun Chakervarti Oct 10 '18 at 10:42

@VarunChakervarti it seems like the server is simply wrong, so if you're able to do that, then you should. If you're integrating with a system that is out of your hands and it's doing things incorrectly, you'd have little choice but to follow suit. But if you can make both systems use a valid accepted common format, that is the better way forward. – VLAZ Oct 10 '18 at 10:44

@vlaz Thank you for your help !! – Varun Chakervarti Oct 10 '18 at 10:49
@DmitryParzhitsky Thank you for your help !! – Varun Chakervarti Oct 10 '18 at 10:49
I have to change the backend code. – Varun Chakervarti Oct 10 '18 at 10:50
It isn't an array in the first place @VarunChakervarti. The so-called "array" for which "response" is the key, is actually a string, since it is enclosed in double quotes `" "`,. – Harshith Rai Oct 10 '18 at 11:26
