Question

I have seen this in a piece of JS code:

var {status, headers, body} = res;

What does it do?

Answer 1

nice method to set few variables at once from an object
(open firebug and paste this to console)

var status=4;
var headers=4;
var body=4;

var res = {status:1, headers:2, body:3};
window.alert(status);
var {status, headers, body} = res;
window.alert(status);
