I know how to use objects, but I wonder... Is it possible to convert object key like this:

{"fname":"peter", "lastname":"parker"}

Into this?

var fname = "peter";
var lname = "parker";

  • Why would you do this? Simply access to the object property? Like this: `var fname = yourobject.fname; var lname = yourobject.lastname;` – briosheje Aug 04 '14 at 07:14

    You can create global variables from the above by attaching properties into the `window` object (if you are on a browser based execution environment). You cannot possibly introduce dynamically named function scoped (local) variables. – techfoobar Aug 04 '14 at 07:14

    While this is possible, I would strongly suggest instead assigning the object to a variable with a short name and then doing `o.fname` instead of `fname`. – user2357112 Aug 04 '14 at 07:14

  • The only solution that may come to my mind involve creating a closure with manually written argument names - nothing really usable. It's not that we all never thought about it, mind you. But in the end it's not just worth the effort. – MaxArt Aug 04 '14 at 07:17

I know it is old question but a method you could use is:

const obj = {"fname":"peter", "lastname":"parker"};
const { fname, lastname } = obj;
console.log(fname); // prints "peter"
console.log(lastname); // prints "parker"

Maybe it helps to someone.

try this to fetch keys:

  var keys=Object.keys({"fname":"peter", "lastname":"parker"});

it returns an array with length of 2;

result: keys[0]="fname" & keys[1]="lastname"
