Good work.

Some optimizations:

If the goal is to return the length of arr at the end, it’s simpler (and less memory) to increment a count number variable rather than pushing to arr.

You also don’t need to reset temp as it will be reset each time the for block loops.

var findNumbers = nums => nums.reduce((acc, n) => {
  if (String(n).length % 2 === 0) { acc.push(n); }
  return acc;
}, []);
