How to extract all the keys and values from the above object? When I printed res.body['kind'] , it printed only the first key in the object. And when I tried to print res.body['items'] , it threw an error items not defined. How to extract the items list from the object

Edit: I am using unirest node module to get the content from the api:

  var req = unirest(
    "GET",
    "https://www.googleapis.com/customsearch/v1?key=<key here>&cx=<cx here>&q=covid+news+articles&g1=ca"
  );
  req.end(function (res) {
    if (res.error) throw new Error(res.error);

    console.log(res.body);
  });

  });

When I printed res.body , I got the above dictionary. I want to extract all the keys and their respective values from above dictionary using res.body

Answer 1

I got the solution. I used Object.keys(res.body) to get all the keys from the object. I got this output when I printed Object.keys(res.body) :

[ 'kind', 'url', 'queries', 'context', 'searchInformation', 'items' ]

I then printed items in the res.body using res.body.items
