selecton/src/js/sortArraybyArr.js

Selecton.js combines a searchbar and a dropdown menu with nested child lists.

export default function(keyArr, arr){
    var sorted = [];

    keyArr.forEach(function(key) {

        var found = false;

        arr = arr.filter(function(item) {

            if(!found && item.key === key) {

                delete item._temporarilyHighlighted_;

                sorted.push(item);

                found = true;

                return false;
            }

            return true;

        });

    });

    return sorted;
}
