I manage to parse a json url with java code previously but need to migrate it to javascript now. When I parse using JavaScript, syntaxerror: Unexpected token I occurred

```
SyntaxError: Unexpected token i in JSON at position 2

```

My javascript is as below:

```
//scrap singapore
function topVolumeGainerLosersSingapore(type) {
$ionicLoading.show();

var url = "http://www.sgx.com/JsonRead/JsonData?qryId=RStock&timeout=30";

$http({
method: 'GET',
url: url,
transformResponse: undefined,
headers: {
"Content-Type":"text/plain",
"Accept":"text/plain"
}
}).then(function success(response) {
// this function will be called when the request is success
var text = response.data;
//console.log(text);
var replaceData = text.substring(text.indexOf("&&")+2);
//console.log(replaceData);
var newData = JSON.parse(replaceData);
console.log(newData);

}, function error(response) {
// this function will be called when the request returned error status
$ionicLoading.hide();
console.log(response);
});
}

```

The java code can parse correctly with no error for the same url

```
public class MainActivity extends AppCompatActivity {

    private static final String TAG = MainActivity.class.getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        new AsyncTas().execute();
    }

    private class AsyncTas extends AsyncTask<Void,Void,Void>{

        @Override
        protected Void doInBackground(Void... voids) {
            HttpURLConnection urlConnection = null;
            String urlString = "http://www.sgx.com/JsonRead/JsonData?qryId=RStock&timeout=30";
            try {
                urlConnection = (HttpURLConnection) new URL(urlString).openConnection();
                //String result = readIt(new BufferedInputStream(urlConnection.getInputStream()));
                BufferedReader bufferedReader = new BufferedReader(
                        new InputStreamReader(urlConnection.getInputStream()));

                // Grab the results
                StringBuilder log = new StringBuilder();
                String line;
                while ((line = bufferedReader.readLine()) != null) {
                    log.append(line + "\n");
                }
                String result = log.toString();

                result = result.substring(result.indexOf("&&") + 2);
                JSONObject jo = new JSONObject(result);

                Log.e(TAG, "doInBackground: "+result);
            } catch (IOException e) {
                e.printStackTrace();
            } catch (JSONException e) {
                e.printStackTrace();
                Toast.makeText(getApplicationContext(),"Unable to parse json "+e.getMessage(),Toast.LENGTH_LONG).show();
            }
            return null;
        }
    }
}

```

The desired output is as below:

```
