  4. * This method is like `_.set` except that accepts `updater` to produce the
  5. * value to set. Use `_.updateWith` to customize `path` creation. The `updater`
  6. * is invoked with one argument: (value).
  7. *
  8. * **Note:** This method mutates `object`.

  14. * @param {Object} object The object to modify.
  15. * @param {Array|string} path The path of the property to set.
  16. * @param {Function} updater The function to produce the updated value.
  17. * @returns {Object} Returns `object`.
