+ * This method is like `_.isMatch` except that it accepts `customizer` which
+ * is invoked to compare values. If `customizer` returns `undefined` comparisons
+ * are handled by the method instead. The `customizer` is invoked with three
+ * arguments: (objValue, srcValue, index|key, object, source).
+ *
+ * @static
+ * @memberOf _
+ * @category Lang
+ * @param {Object} object The object to inspect.
+ * @param {Object} source The object of property values to match.
+ * @param {Function} [customizer] The function to customize comparisons.
+ * @returns {boolean} Returns `true` if `object` is a match, else `false`.
+ * @example
+ *
+ * function isGreeting(value) {
+ *   return /^h(?:i|ello)$/.test(value);
+ * }
+ *
+ * function customizer(objValue, srcValue) {
+ *   if (isGreeting(objValue) && isGreeting(srcValue)) {
+ *     return true;
+ *   }
+ * }
+ *
+ * var object = { 'greeting': 'hello' };
+ * var source = { 'greeting': 'hi' };
+ *
+ * _.isMatchWith(object, source, customizer);
