Get the element in the array with the max value of a property using jQuery

I have an array of a custom JavaScript object which has a property named order. I have an array of this object, and I want to get the item with the highest "order".

Since I'm relatively new to jQuery, and coming from a C# background this is one of the instances where I highly appreciate LINQ :)

Anyway, to cut a long story short, I've checked the following links but they only return the value and not a reference of the array element itself... So a little help in changing that to return the element would be appreciated.

jQuery min/max property from array of elements

element with the max height from a set of elements

The custom object in question(which I have an array of) is as follows:

var severity = function (key, value, order) {
    this.key = key;
    this.value = value;
    this.order = order;
};

array[array.map((o)=>o.order).indexOf(Math.max(...array.map((o)=>o.order)))]

DEMO :

let array=[{order:3},{order:5},{order:2},{order:2}];

console.log(
  array[array.map((o)=>o.order).indexOf(Math.max(...array.map((o)=>o.order)))]
)

try this:

function getHighest(array, value){
  return array.sort(function(a,b){ b[value] - a[value] })[0];
}

Sort array and pop the last object in array

function sortObj(a, b){
     return a.order < b.order ? 0 : 1;
}
obj.sort(sortObj)   
var highest =obj.pop();

Maybe I got you wrong... but is that you are looking for?

function getHighest(array) {
    var max = {};
    for (var i = 0; i < array.length; i++) {
        if (array[i].order > (max.order || 0))
            max = array[i];
    }
    return max;
}

// var array = [object, object, object ...];
var highest = getHighest(array);
