I have the solution here, but I don’t understand the if statement used because It does not seem complete to me. It does not seem to give a requirement of (func(num)), it just says always return num. I’m confused again…
function findElement(arr, func) {
let num = 0;
for (let i = 0; i < arr.length; i++) {
num = arr[i];
if (func(num)) {
return num;
}
}
return undefined;
}
findElement([1, 2, 3, 4], num => num % 2 === 0);
