+- Use `Array.prototype.map()` and `Array.prototype.slice()` to map each element to an array of `n` consecutive elements.

+```js
+const findConsecutive = (arr, n) =>
+  arr.slice(n - 1).map((v, i) => arr.slice(i, i + n));
+```
+
+```js
+findConsecutive([1, 2, 3, 4, 5], 2);
+// [[1, 2], [2, 3], [3, 4], [4, 5]]
+```
