	/**
	 * An alternative to `_.reduce`; this method transforms `object` to a new
	 * `accumulator` object which is the result of running each of its own
	 * enumerable string keyed properties thru `iteratee`, with each invocation
	 * potentially mutating the `accumulator` object. If `accumulator` is not
	 * provided, a new object with the same `[[Prototype]]` will be used. The
	 * iteratee is invoked with four arguments: (accumulator, value, key, object).
	 * Iteratee functions may exit iteration early by explicitly returning `false`.
	 *
	 * @static
	 * @memberOf _
	 * @since 1.3.0
	 * @category Object
	 * @param {Object} object The object to iterate over.
	 * @param {Function} [iteratee=_.identity] The function invoked per iteration.
	 * @param {*} [accumulator] The custom accumulator value.
	 * @returns {*} Returns the accumulated value.
	 * @example
	 *
	 * _.transform([2, 3, 4], function(result, n) {
	 *   result.push(n *= n);
	 *   return n % 2 == 0;
	 * }, []);
	 * // => [4, 9]
	 *
	 * _.transform({ 'a': 1, 'b': 2, 'c': 1 }, function(result, value, key) {
	 *   (result[value] || (result[value] = [])).push(key);
	 * }, {});
	 * // => { '1': ['a', 'c'], '2': ['b'] }
