Find the highest number in array of objects.

getMax.js

var array = [ 
  			    {"name":"dheeraj"},
            {"name":"download"},
            { "name":"code"},
            {"name":"bookbookbookbook"},
             {"name":"book"}
           ];

function getMax() {
 return array.reduce((max, p) => p.name.length > max ? p.name.length : max, array[0].name.length);
}

//OR
function getMax() {
 return Math.max.apply(Math,array.map(function(o){return o.name.length;}))
}

It will return the longest name.
var _get_max_name = array.reduce((prev, current) => (prev.name.length > current.name.length) ? prev : current);
