Question

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?

But using these functions is much more powerful than interating. For example, you can chain multiple map, filter .. etc.

Why did they add numbers to JS when you can just invent your own numbers using church encoding (functions) or strings?
