javascript - I'm trying to raise numbers to their consecutive powers and my code isn't working -

https://codepen.io/aholston/pen/zjbrjd

the codepen link has commented code actual instructions in html

otherwise.... have write function takes 2 params(a , b) , takes numbers between 2 params (a-b) , put every number can added consecutive fowers , equal number new array. ex: 89 = 8^1 + 9^2 = 89 or 135 = 1^1 + 3^2 + 5^3 = 135

function sumdigpow(a, b) {     // code here     var numbers = [];     var checknum = [];     var finalnum = [];     var total = 0;     (var = 1; <= b; i++) {         if (i >= && <= b) {             numbers.push(i);         }     }      (var x = 0; x < numbers.length; x++) {         var checknum = numbers[x].tostring().split('');         if (checknum.length == 1) {             var = parseint(checknum);             finalnum.push(together);         } else if (checknum.length > 1) {             var = checknum.join('');             var tognumber = parseint(together);              (var y = checknum.length; y > 0; y--) {                 total += math.pow(checknum[y - 1], y);             }             if (total == tognumber) {                 finalnum.push(tognumber);             }          }     }     return finalnum; } 

try this:

function listnum(a, b) {   var finalnum = [];   (var = a; <= b; i++) {     var x = i;     var y = i;     var tot = 0;     j = i.tostring().length;     while (y) {       tot += math.pow((y%10), j--);       y = math.floor(y/10);     }     if (tot == x)     finalnum.push(i);   }   return finalnum; } console.log(listnum(1, 200));
