Join values within multiple objects

Question

I got the below object data which I need to join together, how can I achieve the output below provided that "foo" and "bar" would always have the same child elements.

{
  "foo": {
    "aaa": 1,
    "bbb": 2,
    "ccc": 3,
  },
  "bar:" {
    "aaa": "One",
    "bbb": "Two",
    "ccc": "Three",
  }
}

Expected output to be

<li>1 One</li>
<li>2 Two</li>
<li>3 Three</li>

Try this

var foobar = {
  "foo": {
    "aaa": 1,
    "bbb": 2,
    "ccc": 3
  },
  "bar": {
    "aaa": "One",
    "bbb": "Two",
    "ccc": "Three"
  }
};

let mappedArray = Object.keys(foobar.bar).map(xxx=> "<li>" + foobar.foo[xxx] + " " + foobar.bar[xxx] + "</li>");
console.log(mappedArray.join("\n"));
