JSON parsing issue in javascript

Question

I have below result returned from python script

{"a_paget_wilkes": "\/speaker\/a_paget_wilkes.json",
"aaron_clark": "\/speaker\/aaron_clark.json",
"aaron_dunlop": "\/speaker\/aaron_dunlop.json",
"aaron_ernst": "\/speaker\/aaron_ernst.json",
"aaron_hurst": "\/speaker\/aaron_hurst.json",
"abigail_miller": "\/speaker\/abigail_miller.json",
"abner_kauffman": "\/speaker\/abner_kauffman.json"}

So it is pretty well formatted JSON I believe. Javascript variable which has above data is called jsondata. Now in the chrome developer tool console when I try to access key valye pair by typing jsondata. I expect all keys to be listed as suggestion, but it shows me string properties like length, anchor, big, blink etc... instead

I tried even JSON.stringify first and then JSON.parse but still the same!!!

Any idea what is wrong in here?

jsondata is apparently a string containing your JSON, rather than a JavaScript object that would result from parsing your JSON.

To parse it, use JSON.parse.

I tried even JSON.stringify first and then JSON.parse but still the same!!!

JSON.stringify will take you in the wrong direction — it will wrap your entire string in a JSON string — and JSON.parse will only undo the JSON.stringify (recovering your original string), not parse your original string.

You need to call JSON.parse without calling JSON.stringify first.

Now I am getting below Uncaught SyntaxError: Unexpected token ' in JSON at position 1 at JSON.parse (<anonymous>) at index.js:16 code where I parse it is

pyshell.PythonShell.run('py/speakers.py', null, function (err, res) {         if (err){             alert('Error :' + err);         } else {             var jsonDat = JSON.parse(res[2].toString());             console.log(jsonDat);         }     });

No wait....I just got what I was doing wrong! I was returning json.loads from my python script instead of json.dumps. I just corrected that and now all is well!!! Thanks for help, much appreciated.
