Either way it goes, there's a lot of ways to do this that are all trivial.

If you need to find the length of a filtered array IMO it makes more sense
and is more obvious to just use filter().

All the iteration methods are a specific case of reduce, in that you can
implement them all with reduce.

Isn't that just a specific case of Array.prototype.reduce?
```js
const evenNumberCount = [1,2,3,4,5].reduce((acc, val) => { !(val % 2)
&& ++acc; });
```

Hi everyone. This is proposal for Array.prototype.count (or countOf) method
which allow to count specific elements in an array.
```js
const evenNumberCount = [1, 2, 3, 4, 5].count(num => num % 2 === 0);
```
Instead of
```js
const evenNumberCount = [1, 2, 3, 4, 5].filter(num => num % 2 ===
6 matches
