* This method is like `flatMap` except that it recursively flattens the

*
* @since 4.7.0
* @category Collection
* @param {Array|Object} collection The collection to iterate over.
* @param {Function} iteratee The function invoked per iteration.
* @returns {Array} Returns the new flattened array.
* @see flatMap, flatMapDepth, flatten, flattenDeep, flattenDepth, map, mapKeys, mapValues
* @example
*
* function duplicate(n) {
* return [[[n, n]]]
* }
*
* flatMapDeep([1, 2], duplicate)
* // => [1, 1, 2, 2]
