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 === 0).length;

```
