Multiline object in JavaScript. How to loop through it?

Question

I have an object in javascript

var o = [
  {city: 'armenia', population: 300000}, 
  {city: 'russia', population: 1200000}
];

I need to loop through it; please help

That's an array you have there. You can loop through it like any other array... — Jonathan, Jun 20 '14 at 13:32
@Jonathan its an array of objects, you can't loop thru the objects like the array. — Jay Harris, Jun 20 '14 at 13:34

This question been answered before. Needless to say loop thru the array using the length property and loop thru the object using a foreach loop. for each...in

for (var i = 0; i < o.length; i++) {
      var obj = o[i];

      for (var key in obj) {
           // key
           console.log(key);

           // value
           console.log(obj[key]);
      }
 }

o.forEach(function (c) {
  console.log(c.city, c.population); // "armenia" 300000, "russia" 1200000
})

or

for(var i = 0; i < o.length; i++) {
  console.log(o[i].city, o[i].population);
}
