    "Restaurants": [
        {
            "RestrntArea": "Home"
        },
        {
            "RestrntArea": "Office"

        },
        {
            "RestrntArea": "Office"

        }

That's not JSON. If you're dealing with JavaScript source code, unless you're talking about something *in a string*, it's not JSON. — T.J. Crowder, Jun 21 '15 at 17:46

Hi @Preethi, what constitutes a duplicate? Duplicate key, duplicate value or both key and value being the same? — Greg B, Jun 21 '15 at 17:47

Try this.

 var responsefromserver = {
        "Restaurants": [{
            "RestrntArea": "Home"
        }, {
            "RestrntArea": "Office"
        }, {
            "RestrntArea": "Office"
        }]
    };

    var html = [];
    for (var i = 0; i < responsefromserver.Restaurants.length; i++) {
        var name = responsefromserver.Restaurants[i].RestrntArea;
        if(html.indexOf(name)==-1)
              html.push(name);
    }

    alert(html.join(''));
