@ -5,10 +5,9 @@ Checks if the given number is an armstrong number or not.
Convert the given number into array of digits. Use `Math.pow()` 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`. Convert the given number into array of digits. Use `Math.pow()` 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 ```js
const isArmstrongNumber = digits => { const isArmstrongNumber = num => {
let total = 0, arr = (digits+"").split(""); let arr = (num+"").split("");
arr.map(d => total += Math.pow(parseInt(d), arr.length)) return arr.reduce((a, d) => parseInt(a) + Math.pow(parseInt( d ), arr.length), 0) == num ? true : false
if(total === digits) return true; return false;
