How to check if a number is an Armstrong number?

On each iteration, the last digit of num is stored in remainder. Then, remainder is powered by 3 (number of digits) using Math.pow () function and added to result. Then, the last digit is removed from originalNumber after division by 10. Finally, result and number are compared. If equal, it is an Armstrong number. If not, it isn’t.
