Display Armstrong Numbers Between 1 to 1000 using Array Methods
We can also use JavaScript array methods to make the code more concise and functional. In this approach, we convert the number to a string, split it into an array of digits, and then use the reduce method to calculate the sum of each digit raised to the power of the number of digits.
Javascript
function isArmstrong(number) { return number === number .toString() .split('') .reduce((sum, digit, _, { length }) => sum + Math.pow(digit, length), 0); } // Driver code N = 1000; for (let i = 1; i <= N; i++) { if (isArmstrong(i)) { console.log(i); } } |
Output
1 2 3 4 5 6 7 8 9 153 370 371 407
