7 * Creates an object composed of the `object` properties `predicate` returns

10 * @static
11 * @memberOf _
12 * @since 4.0.0
13 * @category Object
14 * @param {Object} object The source object.
15 * @param {Function} [predicate=_.identity] The function invoked per property.
16 * @returns {Object} Returns the new object.
17 * @example
18 *
19 * var object = { 'a': 1, 'b': '2', 'c': 3 };
