Description

Cree una función que examine una matriz (primer argumento) y devuelva el primer elemento de la matriz que pase una prueba de verdad (segundo argumento). Si ningún elemento pasa la prueba, devuelva indefinido. Recuerda usar Read-Search-Ask si te atascas. Trate de emparejar el programa. Escribe tu propio código.

Instructions

Tests

tests:
  - text: '<code>findElement([1, 3, 5, 8, 9, 10], function(num) { return num % 2 === 0; })</code> debe devolver 8.'
    testString: 'assert.strictEqual(findElement([1, 3, 5, 8, 9, 10], function(num) { return num % 2 === 0; }), 8, "<code>findElement([1, 3, 5, 8, 9, 10], function(num) { return num % 2 === 0; })</code> should return 8.");'
  - text: '<code>findElement([1, 3, 5, 9], function(num) { return num % 2 === 0; })</code> debe devolver undefined.'
    testString: 'assert.strictEqual(findElement([1, 3, 5, 9], function(num) { return num % 2 === 0; }), undefined, "<code>findElement([1, 3, 5, 9], function(num) { return num % 2 === 0; })</code> should return undefined.");'

Challenge Seed

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