Finders Keepers-what does this asks to do?

Tell us what’s happening:
I am trying to understand what is this variable doing? is this variable mandatory or part of a for loop?

let num = 0;

I understand I need to do a foot loop to look through the array AND the function.

Your code so far

function findElement(arr, func) {
let num = 0;
return num;

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

It is a bit confusing, but yes will do that, thanks!

How would you advise to pass the first element in the array that passes a truth test?
I understand is an evaluation but using the === would do the job?
Syntax is the issue

first you need to be sure you understand how to make the element undergo the truth test

and it depends what you are comparing

I found on Stackoverflow that someone asked about this challenge so I will use .filter to make sure the element passes the test in the function
