This program checks whether a given number is an Armstrong number using a for loop.

Armstrong Number in JavaScript Using for Loop

An Armstrong number (also known as a narcissistic number) is a number that is equal to the sum of its own digits raised to the power of the number of digits. For example:
<ul>
<li dir="ltr" aria-level="1">
153 is an Armstrong number because
</li>
<li dir="ltr" aria-level="1">
9474 is an Armstrong number because
</li>
</ul>

This concept is commonly used in programming to demonstrate loops, conditions, and mathematical operations. In this tutorial, we will explore how to implement programs to check the Armstrong number in JavaScript. Whether you're writing an Armstrong number in js for a single number or a range, this guide has all the examples.
