/**
 * Creates an array of values by running each property of `object` thru
 * `iteratee`. The iteratee is invoked with three arguments: (value, key, object).

 * @name mapObjVals
 * @since 5.0.0-beta.6
 * @memberOf loop
 *
 * @param {Object} object The object to iterate over.
 * @param {Function} iteratee The function invoked per iteration.
 * @return {Array} Returns the new mapped array.

 *
 * @example
 *
 *   const square = n => n * n
 *   map({ 'a': 4, 'b': 8 }, square)
 *   //=> [16, 64] (iteration order is not guaranteed)
