| * This method is like `get` except that if the resolved value is a | |
| * function it's invoked with the `this` binding of its parent object and | |
| * its result is returned. | |
| * | |
| * @since 0.1.0 | |
| * @category Object | |
| * @param {Object} object The object to query. | |
| * @param {Array|string} path The path of the property to resolve. | |
| * @param {*} [defaultValue] The value returned for `undefined` resolved values. | |
| * @returns {*} Returns the resolved value. | |
| * @example | |
| * | |
| * const object = { 'a': [{ 'b': { 'c1': 3, 'c2': () => 4 } }] } | |
| * | |
| * result(object, 'a[0].b.c1') | |
| * // => 3 | |
| * | |
| * result(object, 'a[0].b.c2') | |
| * // => 4 | |
| * | |
| * result(object, 'a[0].b.c3', 'default') | |
| * // => 'default' | |
| * | |
| * result(object, 'a[0].b.c3', () => 'default') | |
| * // => 'default' | |
