I would like to give some feedback about ...

I'm being able to run the code snippet both on devtools and node, the code gives the the correct answers in all tests, but when I try submitting it's not being accepted

function hammingDistance(n, m){
n = (n).toString(2)
n = ("0".repeat(8 - n.length) + n).split("")
m = (m).toString(2)
m = ("0".repeat(8 - m.length) + m).split("")

var total = 0;

n.forEach((el, index) => {
    if (el !== m[index]) {

return total
