Issue with httpmodule response

Hi,

 

I am facing issue in nativescript typescript mobile application. I am getting response in following format.

 

[[{
JS: "UserId": T325,
JS: "UserName": "SD234",
JS: "Password": "test@1",
JS: "UserType": "DLER",
JS: "SapId": "10009DS457",
JS: "Mobile": "9898891212",
JS: "Email": "[email protected]",
JS: "Status": "Blocked",
JS: "Password1": "",
JS: "Password2": "",
JS: "Password3": "",
JS: "DateCreated": "1900-01-01T00:00:00.000Z"
JS: }]] 

 

I need to access UserId. Please suggest.
