You may try this:

var xx={"1632":45,"1856":12,"1848":56,"1548":34,"1843":88,"1451":55,"4518":98,"1818":23,"3458":45,"1332":634,"4434":33};


var z=_.keys(_.pick(xx, function(value, key, object) {
return (value==_.min(_.values(xx)));  
}))[0];

document.getElementById("my_div").innerHTML=z;

<script src="http://underscorejs.org/underscore-min.js"></script>

<div id="my_div"> </div>

A 3rd party library underscore.js has been used. you should try it:
