Armstrong Number in Javascript: An Incredible Insight
An Armstrong number in JavaScript, also known as a narcissistic number or a pluperfect digital invariant, is a number equal to the sum of its own digits, each raised to the power of the number of digits. In other words, if you take an n-digit number and raise each digit to the nth power, and then sum these values, if the result is the original number, it is an Armstrong number.
