+### nthElement
+
+Returns the nth element of an array.
+
+Use `Array.slice()` to get an array containing the nth element at the first place.
+If the index is out of bounds, return `[]`.
+Omit the second argument, `n`, to get the first element of the array.
+
+```js
+const nthElement = (arr, n=0) => (n>0? arr.slice(n,n+1) : arr.slice(n))[0];
+// nth(['a','b','c'],1) -> 'b'
+// nth(['a','b','b']-2) -> 'a'
+```
