 5   * This method is like `_.isMatch` except that it accepts `customizer` which
 6   * is invoked to compare values. If `customizer` returns `undefined`, comparisons
 7   * are handled by the method instead. The `customizer` is invoked with five
 8   * arguments: (objValue, srcValue, index|key, object, source).

14   * @param {Object} object The object to inspect.
15   * @param {Object} source The object of property values to match.
16   * @param {Function} [customizer] The function to customize comparisons.
17   * @returns {boolean} Returns `true` if `object` is a match, else `false`.

20   * function isGreeting(value) {
21   *   return /^h(?:i|ello)$/.test(value);
22   * }

25   *   if (isGreeting(objValue) && isGreeting(srcValue)) {
