import { RecordIteratee } from "./types";
/**
 * This method is like `invert` except that the inverted object is generated
 * from the results of running each element of `object` thru `iteratee`. The
 * corresponding inverted value of each inverted key is an array of keys
 * responsible for generating the inverted value. The iteratee is invoked
 * with one argument: (value).
 *
 * @since 5.11.0
 * @category Object
 * @param object The object to invert.
 * @param iteratee The iteratee invoked per element.
 * @returns Returns the new inverted object.
 * @example
 *
 * ```js
 * const object = { 'a': 1, 'b': 2, 'c': 1 }
 *
 * invertBy(object, value => `group${value}`)
 * // => { 'group1': ['a', 'c'], 'group2': ['b'] }
 * ```
