[`for...in...`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...in) is for objects: "_iterates over the enumerable properties of an object, **in arbitrary order**._". `posts` is an array, hence you should be using [`for`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for) (Why? -> [Why is using “for…in” with array iteration a bad idea?](http://stackoverflow.com/questions/500504/why-is-using-for-in-with-array-iteration-a-bad-idea) — Andreas, Feb 08 '17 at 09:32

Check this fiddle

var details = new Array();
var dates = new Array();
for (var i = 0; i < resulttable.posts.length; i++) {
  dates = dates.concat(resulttable.posts[i].days.Date);
  details = details.concat(resulttable.posts[i].days.details);
}
console.log(details);
console.log(dates);

Or

var details = new Array();
var dates = new Array();
for (post of resulttable.posts) {
  dates = dates.concat(post.days.Date);
  details = details.concat(post.days.details);
}
console.log(details);
console.log(dates);

Thanks. How about adding a function for participants in details object. like how we use object class for arraylist in java! — SreeAndroidDev, Feb 08 '17 at 10:14
