cannot parse json (body) object in nodejs

Question

I am very new to Node.JS, can anyone help in below issue.

I am calling REST API and it is returning response body wiht JSON object. But i am not able to parse it properly.

I tried body.destination_addresses[0] to retrieve value but doesn't work.

Here is my code sample

 var parsedjson=JSON.parse(body);
 body.destination_addresses[0];

with parsing I am able to retrieve value of body.destination_addresses[0] but failed to retrieve "parsedjson.rows.elements[1].distance.text" value.

How can I retrieve distance value from JSON.

sample json

body:
{
   "destination_addresses" : [
      "458-500 St Johns Pl, Brooklyn, NY 11238, USA",
      "395 4th Ave, Brooklyn, NY 11215, USA"
      ],
   "origin_addresses" : [ "127 Tech Pl, Brooklyn, NY 11201, USA" ],
   "rows" : [
      {
         "elements" : [
            {
               "distance" : {
                  "text" : "2.3 mi",
                  "value" : 3624
               },
               "duration" : {
                  "text" : "15 mins",
                  "value" : 899
               },
               "status" : "OK"
            }
  ]
      }
   ],
   "status" : "OK"
}

Your elements array has only one item so you can't get at index 1

As per your sample try this code

body.rows[0].elements[0].distance.text

You need to clear your basic JavaScript and how to use array

hi,thanks for the response. Still no luck i tried body.rows[i].elements[i].distance.text; (here value of i = 0). error msg: "TypeError: Cannot read property 'elements' of undefined"" .Do you have any idea. [FYI, in my response i have more than 10 values in elements array thats why mentioned elements[1] in my question].

That should work in your case, you are doing something wrong cross check your code, you can post your all response to help
