 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
-const isArmstrongNumber = digits =>{
+const isArmstrongNumber = digits => {
 	let total = 0, arr = (digits+"").split("");
-	arr.map(d =>total += Math.pow(parseInt(d), arr.length))
+	arr.map(d => total += Math.pow(parseInt(d), arr.length))
 	if(total === digits) return true; return false;
