How to get values from JS object

Question

I am working on the demo code below. Why am I not able to extract values from the object?

var obj = {
  webSiteName: 'StackOverFlow',
  find: 'anything',
  onDays: ['sun', 'mon',
    'tue',
    'wed',
    'thu',
    'fri',
    'sat',
    {
      name: "jack",
      age: 34
    },
    {
      manyNames: ["Narayan", "Payal", "Suraj"]
    },
  ]
};


console.log(obj.onDays[2]);
console.log(obj.onDays.manyNames[1]);

The first one works fine, the second should be `obj.onDays[8].manyNames[1]` — 4castle, Oct 02 '17 at 04:12

The manyNames object is at the 8th index of the array, so therefore you need this:

console.log(obj.onDays[8].manyNames[1]);

For jack:

console.log(obj.onDays[7].name);

Or age:

onsole.log(obj.onDays[7].age);

You should understand the basic difference between array and object.

Whenever you deal with an Array, access by index.

arr[index]; // obj["onDays"][7]["name"];

Whenever you deal with an Object, access by the property.

obj[property] or obj.property // obj["find"];
