+
+Creates a function that gets the argument at index `n`. If `n` is negative, the nth argument from the end is returned.

+Use `Array.slice()` to get the desired argument at index `n`.
+
+```js
+const nthArg = n => (...args) => args.slice(n)[0];
+```
+
+<details>
+<summary>Examples</summary>
+
+```js
+const third = nthArg(2);
+third(1, 2, 3); // 3
+third(1, 2); // undefined
+const last = nthArg(-1);
+last(1, 2, 3, 4, 5); // 5
