--description--
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.
--hints--
findElement([1, 3, 5, 8, 9, 10], function(num) { return num % 2 === 0; }) should return 8.
assert.strictEqual(
findElement([1, 3, 5, 8, 9, 10], function (num) {
return num % 2 === 0;
}),
8
);
findElement([1, 3, 5, 9], function(num) { return num % 2 === 0; }) should return undefined.
assert.strictEqual(
findElement([1, 3, 5, 9], function (num) {
return num % 2 === 0;
}),
undefined
);
--seed--
--seed-contents--
function findElement(arr, func) {
let num = 0;
return num;
}
findElement([1, 2, 3, 4], num => num % 2 === 0);
--solutions--
function findElement(arr, func) {
return arr.filter(func)[0];
}
findElement([1, 2, 3, 4], num => num % 2 === 0);
