Iterate over object properties

This feature allows you to iterate over all enumerable properties of an object, including inherited properties. The provided function is invoked for each property.

const object = { 'a': 1, 'b': 2, 'c': 3 };

forIn(object, function(value, key) {
  console.log(key, value);
});
