JavaScript Object

Object is special type of data with properties and methods. Almost every thing in javascript is an object. 

<script type="text/javascript">

    var arr = new Array(10);

    for (var i = 0; i < 10; i++) {

        //arr[i] = { firstname: 'Kunal', age: 25 + i };

        //OR

        var kunal = new Object();

        kunal.firstname = 'Kunal Maurya';

        kunal.age = 20 + i;

        arr[i] = kunal;

    }

    for (var i = 0; i < 10; i++) {

        var kunal = arr[i];

        document.write(kunal.firstname + " is " + kunal.age + " years old.
");

        //OR

        //document.write("
" + arr[i].firstname + " is " + arr[i].age + " years old.");

    }

</script>
