/** |
|
* This method is like `_.flatMap` except that it recursively flattens the |
|
* mapped results up to `depth` times. |

|
* @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); |
|
* // => [[1, 1], [2, 2]] |
