Can't find the Infinite loop

1

I seem to have an infinite loop here somewhere but I’m not seeing it.
The for loop seems fine to me (but then I’ve been staring at it for awhile) Any thoughts?

function findFibs(num){
  let arr = [1,1];
  let size = arr.length;
  for(let val = 2; val < num; val = arr[size-2] + arr[size-1]){
    arr.push(val);
  }
  return arr;
}

function sumFibs(num) {
  return findFibs(num).reduce((sum, curr)=>{
    return curr % 2 ? sum += curr: sum;
  },0);
}

sumFibs(4);
2

In your for loop size doesn’t change, so val is always 2:

size = 2
val = arr[size-2] + arr[size-1] = arr[0] + arr[1] = 1 + 1 = 2;
