Basic Algorithm Scripting - Finders Keepers

JavaScript

Hi! I could passed this excercise, but was just curious to know why this solution is not correct (the console always returns “undefined”). Thanks in advanced!

Your code so far

function findElement(arr, func) {
  let num = 0;
  for (let i= 0; i <= arr.length; i++){
    num = arr[i];
    if (func(num) === true){
      return num;
    } else{
      return undefined
    }
}
}
console.log(findElement([1, 2, 3, 4], num => num % 2 === 0));

The return statement immediately stops the function, even in the middle of a loop.
