second() Instance Public methods Equal to self[1]. %w( a b c d e ).second # => "b"

split(value = nil) Instance Public methods Divides the array into one or more subarrays based on a delimiting value or the result of an optional block. [1, 2, 3, 4, 5].split(3) # => [[1, 2], [4, 5]] (1..10).to_a.split { |i| i % 3 == 0 } # => [[1, 2], [4, 5], [7, 8], [10]]

third() Instance Public methods Equal to self[2]. %w( a b c d e ).third # => "c"

to(position) Instance Public methods Returns the beginning of the array up to position. %w( a b c d ).to(0) # => ["a"] %w( a b c d ).to(2) # => ["a", "b", "c"] %w( a b c d ).to(10) # => ["a", "b", "c", "d"] %w().to(0) # => []
