```
  var addition=function(num){
    var sumSoFar=0;  
    for(var i=1;i<=num;i++)
        {
         sumSoFar+=num[i];
         return sumSoFar;
         }
         };
        console.log(addition(5));

```

I wrote this with a while loop a little bit ago. It supposed to take a random (num) and return the sum of all numbers from 1 to (num) Im just not figuring out what im doing wrong with the for loop
