-### flattenDepth
-
-Flattens an array up to the specified depth.
-
-Use recursion, decrementing `depth` by 1 for each level of depth.
-Use `Array.reduce()` and `Array.concat()` to merge elements or arrays.
-Base case, for `depth` equal to `1` stops recursion.
-Omit the second element, `depth` to flatten only to a depth of `1` (single flatten).
-
-```js
-const flattenDepth = (arr, depth = 1) =>
-  depth != 1
-    ? arr.reduce((a, v) => a.concat(Array.isArray(v) ? flattenDepth(v, depth - 1) : v), [])
-    : arr.reduce((a, v) => a.concat(v), []);
-```
-
-```js
-flattenDepth([1, [2], 3, 4]); // [1,2,3,4]
-```
