## JavaScript: Tips of the Day

Chunks an array into n smaller arrays

Example:

```const tips_chunkIntoN = (arr, n) => {
const size = Math.ceil(arr.length / n);
return Array.from({ length: n }, (v, i) =>
arr.slice(i * size, i * size + size)
);
}
console.log(tips_chunkIntoN([1, 2, 3, 4, 5, 6, 7,8], 4));
```

Output:

```[[1,2],[3,4],[5,6],[7,8]]
```
