 /**
- * Resolves the value of property `key` on `object`. If the value of `key` is
- * a function it is invoked with the `this` binding of `object` and its result
- * is returned, else the property value is returned. If the property value is
- * `undefined` the `defaultValue` is used in its place.
+ * This method is like `_.get` except that if the resolved value is a function
+ * it is invoked with the `this` binding of its parent object and its result
+ * is returned.
  *
  * @static
  * @memberOf _
  * @category Object
  * @param {Object} object The object to query.
- * @param {string} key The key of the property to resolve.
- * @param {*} [defaultValue] The value returned if the property value
- *  resolves to `undefined`.
+ * @param {Array|string} path The path of the property to resolve.
+ * @param {*} [defaultValue] The value returned if the resolved value is `undefined`.
  * @returns {*} Returns the resolved value.
  * @example
  *
- * var object = { 'user': 'fred', 'age': _.constant(40) };
+ * var object = { 'a': [{ 'b': { 'c1': 3, 'c2': _.constant(4) } }] };
