There’s a specific built-in method called filter. const array = [1,

2, 10, 16];

const filterArray = array.filter(num => num > 5);

console.log(filterArray);

Why did they build this build-in method filter when you can just use a function that can just iterates numbers you can just select on the conditional line?
