/**
 * Creates an array of values by running each property of `object`
 * or index of `array` thru `iteratee`.
 * The iteratee is invoked with three arguments: (value, key, object).
 *
 * @alias mapAnyVals
 * @memberOf loop
 * @since 5.0.0
 * @category Object
 *
 * @param {Object|Array} obj The object or array to iterate over.
 * @param {Function} predicate The function invoked per iteration.
 * @param {Object} [result = {}] initial value, accumulated, output
 * @return {Array|Object} Returns the new mapped array or object
 *
 * @example
 *
 *   const square = n => n * n
 *   map({ 'a': 4, 'b': 8 }, square)
 *   //=> [16, 64] (iteration order is not guaranteed)
