That stack overflow thread is very informative.

If I understand correctly since ES6 there is an order ([The traversal order of object properties in ES6](https://2ality.com/2015/10/property-traversal-order-es6.html)) and on the stack overflow are numerous ways to re-sort the keys.

So JavaScript continues to "improve" itself to the point of no return 🙂.

I used the Stack Overflow replies to come up with this;

```auto
    / **************************************************************************************************
    *
    * Description. Create a new Object, by adding the properties of the old Object in order of the Array of 'keys'
    * If required, add any remaining properties of old Object to new Object
    *
    * @param {Object} object The object to operate on
    * @param {Array} keysInOrder An Array of the keys required, in order to be added
    * @param {boolean} addAll True if all properties of old Object to be added to new Object, false if only keys. Default is true
    * in Array to be added
    *
    * @return {Object} An Object with the properties in 'key' order of the provided Array, plus any other properties in
    * original order
    *
    * @Example let orderedObject = orderObjectProperties({c: 1, a: 2, b: 1}, ['a', 'b'], false) becomes {a: 2, b: 1}
    */

    function orderObjectProperties(object, keysInOrder, addAll = true) {
        let newObject = {}
        // Add the new Object properties in order of 'keys' in Array
        for (const key of keysInOrder) {
            if (Object.keys(object).includes(key) && !Object.keys(newObject).includes(key))
                newObject[key] = object[key]

        }

        // Add any old Object properties not yet added, if required
        if (addAll) {
            for (const key of Object.keys(object)) {
                if (!Object.keys(newObject).includes(key))
                    newObject[key] = object[key]

            }

        }

         return newObject

    } // End Function orderObjectProperties()

```

Perhaps you should add it to the flows, so its easier to find.
