A very good method i found in ruby so just thought to share it with everyone, so i am writing this blog to share and help others. This particular blog is for splitting up of array into many groups. Lets see this as an example below:

1) arr = (1..6).to_a


2) arr.each_slice(2).to_a # => [[1, 2], [3, 4], [5, 6]]

3) arr.each_slice(3).to_a # => [[1, 2, 3], [4, 5, 6]]

4) arr.each_slice(4).to_a # => [[1, 2, 3, 4], [5, 6]]

In the first line we took a range from 1-6 and convert into an array and after that we are splitting it into different sizes

A) In line 2 we specified the size as 2

2) In line 3 we specified the size as 3

3) In line 4 we specified the size as 4 so the first group would be from 1-4 and second would be just 5-6 because we dont have more numbers in the array
