Method: Array#each_slice

Defined in:
lib/nano/enumerable/each_slice.rb

#each_slice(n = nil, &yld) ⇒ Object

Iterates over n elements at a time. If n is not given then the arity of the block determines the slicing quantity.

[1, 2, 3, 4].each_slice(2){ |a,b| ... }

This is a specialized version Enumerable#each_slice but optimized specifically for Array.
