-Checks if the given number is an Armstrong number or not.

-Convert the given number into an array of digits. Use the exponent operator (`**`) to get the appropriate power for each digit and sum them up. If the sum is equal to the number itself, return `true` otherwise `false`.
-
-```js
-const isArmstrongNumber = digits =>
-  (arr => arr.reduce((a, d) => a + parseInt(d) ** arr.length, 0) == digits)(
-    (digits + '').split('')
-  );
-```
-
-```js
-isArmstrongNumber(1634); // true
-isArmstrongNumber(56); // false
