Feature request: chunks

[mcastorina]

First off, thanks for making this great library!

What do you think of adding a chunks(n) function that splits an Array into n-sized Arrays?

Something like..

>>> Array(range(10)).chunks(5)
Array(Array(0, 1, 2, 3, 4), Array(5, 6, 7, 8, 9))

I'd be happy to contribute this feature as well.

[mcastorina]

It would be functionally the same as

arr.splitAt(range(n, arr.length, n))

[Lauriat]

The same result can also be achieved with
arr.splitTo(arr.size // chunkSize)
but adding a chunks() may indeed be useful.
Thanks!

I would prefer splitAt so n doesn't have to divide evenly into the size.

Also, let me know if you would like me to make a PR or not :)

[Lauriat]

It's there now!

[mcastorina]

Awesome!

Another good feature could be windows(n) where n is the window size.

>>> Array(range(6)).windows(3)
Array(Array(0, 1, 2), Array(1, 2, 3), Array(2, 3, 4), Array(3, 4, 5))

Implemented - thanks for your suggestions!
