  5. * This method is like `_.assign` except that it accepts `customizer`
  6. * which is invoked to produce the assigned values. If `customizer` returns
  7. * `undefined`, assignment is handled by the method instead. The `customizer`
  8. * is invoked with five arguments: (objValue, srcValue, key, object, source).
  9. *
  10. * **Note:** This method mutates `object`.

  14. * @since 4.0.0
  15. * @category Object
  16. * @param {Object} object The destination object.
  17. * @param {...Object} sources The source objects.
  18. * @param {Function} [customizer] The function to customize assigned values.
  19. * @returns {Object} Returns `object`.
