I want a combined

Answer 1

the most trivial solution is (in compare to any util lib like underscore.js or similar). pros of it is it works without any dependency.

var result = [];
for(var i = 0; i < arr1.length; i+= 1) {
  item = {};
  item.name = arr1[i].name;
  item.age = arr2[i].age;
  result.push(item);
}
