ascendingSort.js

const persons = [ 
                  { 'name':'luke', 'age':10},
                  { 'name':'leia', 'age':10},
                  { 'name':'vader', 'age':40}                  
                ];

const ascending = x => y => x > y;

const ageSort = (x, y) => ascending(x.age)(y.age);

const nameSort = (x, y) => ascending(x.name)(y.name); 

const ascendingSort = persons.sort(nameSort).sort(ageSort);                         

console.log(ascendingSort);
