/**

* Creates a flattened array of values by running each element through iteratee and flattening the mapped results up to depth times.
|
|
*
|
|
* @template T, R
|
|
* @param collection - The array or object to iterate over.
|
|
* @param [iteratee] - The function that produces the new array elements.
|
|
* @param [depth=1] - The maximum recursion depth.
|
|
* @returns A new array that has been flattened up to the specified depth.
|
|
*
|
|
* @example
|
|
* flatMapDepth([1, 2, 3], n => [[n, n]], 2);

|
* // => [1, 1, 2, 2, 3, 3]
