Javascript: Why are my numbers not being raised to the nth power and being pushed to my array? -

i trying write function takes in number , sums range of digits nth power, seems function not "n-thing" each number in array.

here's code:

function sumdigpow(a, b) {   var premarray = [];   var squaredarray = [];   for(var = a; <= b; i++){     premarray.push(i);    }   for(var j = 0; j < premarray.length; j++){       var squared = ('' + premarray[j]).split('').map(function(v, i){         return math.pow(parseint(v), + 1);       }).reduce(function(a , v){           return + v;       }, 0);         squaredarray.push(squared);     } }  sumdigpow(5,22); 

you pretty on complicated entire thing.

function digpow(n, p){   var total = 0;   var digits = (""+n).split("");    (var = 0; i< digits.length; i++) {     total += math.pow(digits[i], p+i);   }    if(total/n % 1 === 0){     return total/n;   }    return -1; } 

here split first number array. mind string times number can produce number if string of number example: "6".

so split it, iterate through , calculate total result, after check if result divided our start number (n) int , have simple solution. hope helps.
