There is a nested object like that:

var conversation = {

    'John': {

        1: 'Test message 1',

        2: 'Test message 2',

        'Reply': {

            3: 'Test message 3',

            4: 'Test message 4'

        }

    },

    'Jack': {

        5: 'Test message 5',

        6: 'Test message 6'

    }

};

I need to get all final values, so for that example, it is:

Test message 1

Test message 2

Test message 3

Test message 4

Test message 5

Test message 6

How to iterate over the object? Is there any built-in function in jQuery or JavaScript?

You can use some recursion to check to see if the key being iterated over is an object or not, then print:

function printValues(obj) {

    for (var key in obj) {

        if (typeof obj[key] === object) {

            printValues(obj[key]);   

        } else {

            console.log(obj[key]);    

        }

    }

}



printValues(conversation);
