Finders Keepers:Problem

JavaScript
1 
function findElement(arr, func) {
  let num = 0;
  for(let i = 0;i<=arr.length;i++){
    //console.log(arr[i]);
    //console.log(func(arr[i]));
    console.log(`${arr[i]}:${func(arr[i])}`);
    if(func(arr[i]) === true){
      return arr[i];
    }
    else{
      return undefined;
    }
  }
  return num;
}

console.log(findElement([1, 2, 3, 4], num => num % 2 === 0));

Its not returning the true values but rather returning the false ones.
