`for ... of` only iterate over objects that implement `Symbol.iterator`. Native objects don’t do that by default, so `_.forEach` is more useful the `for ... of` even if you are only targeting modern browsers and not compiling the code down to an earlier version of the spec.

That said, you can use `Object.keys`, `Object.values`, or `Object.entries` if you want to iterate over objects that don’t implement `Symbol.iterator`, so if you only need `_.forEach` there is no reason to pull in any libraries.

    Object.entries(object).forEach(([key, value]) => {
      // ...
    });
