How to reshape a Ruby array

Having an array

a = [1, 2, 3, 4, 5, 6]

I want to reshape it to

a = [[1, 2], [3, 4], [5, 6]]

I've had an impression that there was a specific method for this. I've just been through Array class reference, but failed to find it. Does anyone remember?

You can do something like this:

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

Like this, for example:

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