/**

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

|
* mapped results up to `depth` times.

* @static
|
|
* @memberOf _
|
|
* @since 4.7.0
|
|
* @category Collection
|
|
* @param {Array|Object} collection The collection to iterate over.
|
|
* @param {Function} [iteratee=_.identity] The function invoked per iteration.
|
|
* @param {number} [depth=1] The maximum recursion depth.
|
|
* @returns {Array} Returns the new flattened array.
|
|
* @example
|
|
*
|
|
* function duplicate(n) {

|
* return [[[n, n]]];

|
|

|

* _.flatMapDepth([1, 2], duplicate, 2);
