I need to add all the number of some random number like var myNum = ["1233445", "1213332"]; compare the sum of these to like i mean 1+2+3+3..... and the another one 1+2+1+3+3+3.... thanks You can do this...

```var number = 12354987,
output = [],
sNumber = number.toString();

for (var i = 0; i < sNumber.length; i++) {
output.push(sNumber.charAt(i));
}

console.log(output);
```

This will give you an array like

```["1", "2", "3", "5", "4", "9", "8", "7"]
```

You can then iterate through the array and use the parseInt() method to get each individual number and add them together.

```var addedSum

for (var i=0; i < output.length; i++) {
}
```

You could make the above functions as well so you can call it on multiple numbers. However you would need to store each of those numbers into different variables in order to compare the sums of them. something like this:

```function sum(arr) {
var sum = 0;
for (var i = 0; i < arr.length; i++) {
sum += arr[i].split('').map(str => parseInt(str)).reduce((a,b) => a+b);
}
return sum;
}

var sum = sum(['1233445', '1213332']);

console.log(sum);
```
