/**
 * The base implementation of `baseForOwn` which iterates over `object`

 * Iteratee functions may exit iteration early by explicitly returning `false`.
 * @since 5.0.0-beta.6
 * @memberOf loop
 *
 * @param {Object} object The object to iterate over.
 * @param {Function} iteratee The function invoked per iteration.
 * @param {Function} keysFunc The function to get the keys of `object`.
 * @return {Object} Returns `object`.
