How to print all armstrong numbers between 1 to 500 in JavaScript

Answer 1

function armstrong(n) {
    let result = 0, remainder;  
           
    while(n > 0) {  
        remainder = n % 10;  
        n = Math.floor(n / 10);
        result += remainder * remainder * remainder;  
    }  
    return result;
}
          
// 153 = 1*1*1 + 5*5*5 + 3*3*3 = 153 = armstrong
           
for (let i = 1; i <= 500; i++)          
    if (i == armstrong(i))  
        console.log(i);   
 
    
    
   
     
     
/*
run:

153
370
371
407
     
*/
