Answer 1

Yes you can reduce() your array to an object with the keys and the count, like this:

const input = [
  "foo",
   "bar",
   "foo",
   "bar",
   "bar",
   "bar",
   "zoom"
];
const result = input.reduce((total, value) => {
     total[value] = (total[value] || 0) + 1;
     return total;
}, {});
console.log(result);

Hope it helps!
