We Need To Return The Element From An Array That Passes A Function

• Create a function that looks through an array arr and returns the first element in it that passes a 'truth test'. This means that given an element x, the 'truth test' is passed if func(x) is true. If no element passes the test, return undefined.

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

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

• Notes: If a number is evenly divisible by 2 with no remainder, then it is even. You can calculate the remainder with the modulo operator % like this num % 2 == 0 . If a number divided by 2 leaves a remainder of 1, then the number is odd. You can check for this using num % 2 == 1 . 1 % 2 = 1 because its odd 2 % 2 = 0 because its even 4 % 2 = 0 because its even *Answer:

function findElement(arr, func) {
  for (let i = 0; i < arr.length; i++)
  if (func(arr[i])) {
    return arr[i];
  }
  return undefined;
}

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