  4. * Performs a partial deep comparison between `object` and `source` to
  5. * determine if `object` contains equivalent property values.
  6. *
  7. * **Note:** This method is equivalent to `_.matches` when `source` is
  8. * partially applied.
  9. *
  10. * Partial comparisons will match empty array and empty object `source`
  11. * values against any array or object value, respectively. See `_.isEqual`
  12. * for a list of supported value comparisons.
